CLRM-09. INCORPORATING EXTERNAL CONTROL ARM IN MDNA55 RECURRENT GLIOBLASTOMA REGISTRATION TRIAL

e20619 Background: Lurbinectedin monotherapy is currently approved for the treatment of adult patients with metastatic small cell lung cancer (SCLC) with disease progression on or after platinum-based chemotherapy based on the results of a single-arm phase 2 basket trial. The current study established real-world comparator arms (RWCAs) to enable retrospective comparison of the efficacy of lurbinectedin from the trial, notably overall survival (OS) and overall response rate (ORR), to other standard of care treatments. Methods: This exploratory study consisted of two arms, where the 1st arm was the lurbinectedin trial arm (LTA) comprised of data from the SCLC cohort of the trial (NCT02454972) and the 2nd arm was an RWCA sourced from ConcertAI electronic medical records in the US (2010 to 2019). Relevant inclusion and exclusion criteria from the trial were applied to the RWCA to ensure comparability at baseline. Given the absence of Eastern Cooperative Oncology Group performance status (ECOG) for a sizable portion of patients in the RWCA, two RWCA groups were studied, one that excluded patients with reported ECOG > 2 (RWCA1) and the other that excluded patients with reported ECOG > 2 and missing ECOG (RWCA2). Propensity score (PS) weighting was used to further balance measured baseline characteristics between LTA and each RWCA. OS was defined as the time from treatment initiation to death. Weighted cox regression was used to compare OS. ORR was defined as the percentage of patients with a complete or partial response. A weighted two-sample test of proportions was used to compare ORR. Results: This study included 105 patients in LTA and 121 in RWCA1 (74 in RWCA2). After PS weighting, baseline characteristics were mostly similar between LTA and each RWCA. ECOG was balanced between RWCA2 and LTA but was different between RWCA1 and LTA. A numerical median OS benefit of 3.8 and 4.7 months was observed in LTA, compared to RWCA1 and RWCA2, respectively (see table). Probability of survival was greater in LTA compared to RWCAs at 3 and 6 months. ORR was two-fold higher in LTA compared to RWCA1. Consistent findings were seen for LTA compared to RWCA2. Conclusions: Lurbinectedin monotherapy demonstrated improved median OS, lower risk of death at 3 and 6 months, and higher response rate compared to other standard of care treatments in relapsed/refractory SCLC. Future studies with larger sample size powered to detect statistical differences in OS are warranted.[Table: see text]

Observational studies in glaucoma patients can provide important evidence on treatment effects, especially for combination therapies which are often used in reality. But the success relies on the reduction of selection bias through methods such as propensity score (PS) weighting. The objective of this study was to assess the effects of five glaucoma treatments (medication, laser, non-laser surgery (NLS), laser + medication, and NLS + medication) on 1-year intraocular pressure (IOP) change. Data were collected from 90 glaucoma subjects who underwent a single laser, or NLS intervention, and/or took the same medication for at least 6 months, and had IOP measures before the treatment and 12-months after. Baseline IOP was significantly different across groups (p = 0.007) and this unbalance was successfully corrected by the PS weighting (p = 0.81). All groups showed statistically significant PS-weighted IOP reductions, with the largest reduction in NLS group (−6.78 mmHg). Baseline IOP significantly interacted with treatments (p = 0.03), and at high baseline IOP medication was less effective than other treatments. Our findings showed that the 1-year IOP reduction differed across treatment groups and was dependent on baseline IOP. The use of PS-weighted methods reduced treatment selection bias at baseline and allowed valid assessment of the treatment effect in an observational study.

To examine the prognostic relevance of human papillomavirus (HPV) infection for anal squamous cell carcinoma (ASCC) patients treated with chemoradiation (CRT) in the National Cancer Data Base (NCDB). The 2014 NCDB was queried for non-metastatic, histologically confirmed, ASCC patients diagnosed between 2004 and 2013. Patients were required to have HPV status documented in order to be eligible. Patients were then stratified into two groups: HPV+ and HPV-. Univariate analysis (UVA) was performed using the χ2 test for categorical covariates and ANOVA for numerical covariates. Multivariable analysis (MVA) was performed using Cox proportional hazard model for overall survival (OS). Hazard ratios (HRs) and 95% confidence intervals (CIs) were generated for each covariate. To minimize selection bias, propensity score (PS) weighting was implemented to balance OS related variables between the groups including: age, education level, stage, diagnosis year, insurance type, and agent of chemotherapy. A total of 1,063 patients were eligible. Patients were stratified into HPV+ (n=498, 46.8%) and HPV- (n=565, 53.2%). After PS weighting, MVA for OS showed that for men, HPV infection was associated with better OS (HR: 0.60, 95% CI: 0.38-0.96; P=0.034). However, for women, HPV infection did not significantly influence survival (HR: 1.47, 95% CI: 0.96-2.25; P=0.074). To our knowledge, this is the largest patient series evaluating the impact of HPV infection on OS in patients with anal cancer. We found that HPV infection is associated with a statistically significant better survival for men with ASCC. In contrast, for women, HPV infection did not significantly influence survival.

Role of Antimuscarinics Combined With Alpha-blockers in the Management of Urinary Storage Symptoms in Patients With Benign Prostatic Hyperplasia: An Updated Systematic Review and Meta-analysis.

PurposeThis paper extends current propensity score weighting methods for causal inference to better understand disparities in healthcare access across multiple racial groups. By treating each racial group as a distinct entity (or “treatment”) in the causal inference framework, we can assess and evaluate heterogeneity in healthcare outcomes across various racial or ethnic categories. Furthermore, we leverage modern propensity score weighting techniques to address the challenges inherent to multiple group evaluations, such as violations of the positivity assumption, and compare the performance of different propensity score weights.MethodsWe use generalized propensity score methods to assess racial disparities across 4 specific racial or ethnic groups: Whites, Hispanics, Asians, and Blacks. We first calculate weights that standardize the participants’ characteristics and then compare their weighted outcomes. We consider four distinct measures (i.e., causal estimands) and estimation methods: the conventional average treatment effect on the treated (ATT), the ATT trimming, the ATT truncation, and the overlap weighted ATT (OWATT). These estimands are applied under a multi-valued “treatment” framework, where the said “treatment” is defined by non-manipulable racial or ethnic group memberships. Using data from the Medical Expenditure Panel Survey (MEPS), we assess disparities in healthcare expenditures across the 4 racial and ethnic groups.ResultsWe found significant disparities in healthcare expenditure between White participants and all the other racial or ethnic groups when using OWATT and ATT truncation. Conventional ATT and ATT trimming could indicate non-significant difference due to larger variance estimates. Moreover, the conventional ATT was found to be the least efficient estimation method, even when its variance was estimated via non-parametric bootstrapping. Overall, the OWATT emerges as a promising estimation method; it retains the available information from all samples, avoids subjectivity (inherent to choosing thresholds by its competitors) and mitigates judiciously pernicious inferential effects (such as the inflated variance estimates) by extreme propensity score weights.ConclusionWe found that generalized propensity score weighting (GPSW) methods are valuable quantitative tools to standardize and compare characteristics as well as outcomes of non-manipulable groups. This helps assess disparities across multiple racial and ethnic groups, as demonstrated in this study. These methods offer flexible and semi-parametric analysis on the primary causal parameters of interest (such as the racial disparities), with straightforward and intuitive interpretations. In addition, when there is violation of the positivity assumption, OWATT serves as an excellent alternative due to its greater efficiency, evidenced by relatively smaller variance. More importantly, the OWATT uses the entire dataset by assigning weights to all participants, regardless of their propensity score values. This feature of OWATT circumvents the need to specify user-defined thresholds, as required in ATT trimming or truncation, and retains as much data information as possible, leading to more reliable estimation results.

ObjectivesProlonged air leaks are common after thoracic surgery and may be managed with synthetic aerostatic devices. This study assessed the impact of the Neoveil patch on air leak duration, hospital stay, and postoperative pneumonia.MethodsWe conducted a retrospective monocentric study at Amiens University Hospital including adults undergoing lung resection between 2014 and 2024. Patients were divided into three groups: those receiving Neoveil, those not receiving it because of absence of indication, and those operated before its introduction in 2017. For analysis, the two latter groups were pooled as the Non-Neoveil arm. To address confounding, a propensity score was built from baseline covariates with standardized mean difference >5%, and inverse probability weighting was applied. The primary end-point was air leak duration, assessed with weighted linear regression. Secondary outcomes were hospital stay and postoperative pneumonia, analyzed with weighted linear and logistic regression.ResultsAmong 1216 patients, 313 (26%) received Neoveil. Compared with the control group, Neoveil use was associated with shorter air leak duration both before adjustment (−1.01 days; P = .0004) and after adjustment (−0.67 days; P = .0042). Hospital stay was also reduced (−1.88 days before adjustment; −1.09 days after adjustment; P = .0022). No significant difference was observed for postoperative pneumonia after adjustment (adjusted Odds Ratio 0.73, 95% Confidence Interval 0.48-1.11; P = .14).ConclusionsNeoveil use was associated with reduced air leak duration and shorter hospital stay following lung resection, without significant impact on pneumonia. These findings support its potential role in enhancing postoperative recovery and highlight the need for confirmation in prospective multicentre studies.

Brain stimulation and other biological non-pharmacological interventions in mental disorders: An umbrella review

Several rehabilitation programmes are available for individuals after lumbar disc surgery. To determine whether active rehabilitation after lumbar disc surgery is more effective than no treatment, and to describe which type of active rehabilitation is most effective. This is the second update of a Cochrane Review first published in 2002.First, we clustered treatments according to the start of treatment.1. Active rehabilitation that starts immediately postsurgery.2. Active rehabilitation that starts four to six weeks postsurgery.3. Active rehabilitation that starts longer than 12 months postsurgery.For every cluster, the following comparisons were investigated.A. Active rehabilitation versus no treatment, placebo or waiting list control.B. Active rehabilitation versus other kinds of active rehabilitation.C. Specific intervention in addition to active rehabilitation versus active rehabilitation alone. We searched CENTRAL (2013, Issue 4) and MEDLINE, EMBASE, CINAHL, PEDro and PsycINFO to May 2013. We included only randomised controlled trials (RCTs). Pairs of review authors independently assessed studies for eligibility and risk of bias. Meta-analyses were performed if studies were clinically homogeneous. The GRADE approach was used to determine the overall quality of evidence. In this update, we identified eight new studies, thereby including a total of 22 trials (2503 participants), 10 of which had a low risk of bias. Most rehabilitation programmes were assessed in only one study. Both men and women were included, and overall mean age was 41.4 years. All participants had received standard discectomy, microdiscectomy and in one study standard laminectomy and (micro)discectomy. Mean duration of the rehabilitation intervention was 12 weeks; eight studies assessed six to eight-week exercise programmes, and eight studies assessed 12 to 13-week exercise programmes. Programmes were provided in primary and secondary care facilities and were started immediately after surgery (n = 4) or four to six weeks (n = 16) or one year after surgery (n = 2). In general, the overall quality of the evidence is low to very low. Rehabilitation programmes that started immediately after surgery were not more effective than their control interventions, which included exercise. Low- to very low-quality evidence suggests that there were no differences between specific rehabilitation programmes (multidisciplinary care, behavioural graded activity, strength and stretching) that started four to six weeks postsurgery and their comparators, which included some form of exercise. Low-quality evidence shows that physiotherapy from four to six weeks postsurgery onward led to better function than no treatment or education only, and that multidisciplinary rehabilitation co-ordinated by medical advisors led to faster return to work than usual care. Statistical pooling was performed only for three comparisons in which the rehabilitation programmes started four to six weeks postsurgery: exercise programmes versus no treatment, high- versus low-intensity exercise programmes and supervised versus home exercise programmes. Very low-quality evidence (five RCTs, N = 272) shows that exercises are more effective than no treatment for pain at short-term follow-up (standard mean difference (SMD) -0.90; 95% confidence interval (CI) -1.55 to -0.24), and low-quality evidence (four RCTs, N = 252) suggests that exercises are more effective for functional status on short-term follow-up (SMD -0.67; 95% CI -1.22 to -0.12) and that no difference in functional status was noted on long-term follow-up (three RCTs, N = 226; SMD -0.22; 95% CI -0.49 to 0.04). None of these studies reported that exercise increased the reoperation rate. Very low-quality evidence (two RCTs, N = 103) shows that high-intensity exercise programmes are more effective than low-intensity exercise programmes for pain in the short term (weighted mean difference (WMD) -10.67; 95% CI -17.04 to -4.30), and low-quality evidence (two RCTs, N = 103) shows that they are more effective for functional status in the short term (SMD -0.77; 95% CI -1.17 to -0.36). Very low-quality evidence (four RCTs, N = 154) suggests no significant differences between supervised and home exercise programmes for short-term pain relief (SMD -0.76; 95% CI -2.04 to 0.53) or functional status (four RCTs, N = 154; SMD -0.36; 95% CI -0.88 to 0.15). Considerable variation was noted in the content, duration and intensity of the rehabilitation programmes included in this review, and for none of them was high- or moderate-quality evidence identified. Exercise programmes starting four to six weeks postsurgery seem to lead to a faster decrease in pain and disability than no treatment, with small to medium effect sizes, and high-intensity exercise programmes seem to lead to a slightly faster decrease in pain and disability than is seen with low-intensity programmes, but the overall quality of the evidence is only low to very low. No significant differences were noted between supervised and home exercise programmes for pain relief, disability or global perceived effect. None of the trials reported an increase in reoperation rate after first-time lumbar surgery. High-quality randomised controlled trials are strongly needed.

BackgroundThe aim of this review was to systematically review and meta-analyze the effects of yoga on symptoms of schizophrenia, quality of life, function, and hospitalization in patients with schizophrenia.MethodsMEDLINE/Pubmed, Scopus, the Cochrane Library, PsycInfo, and IndMED were screened through August 2012. Randomized controlled trials (RCTs) comparing yoga to usual care or non-pharmacological interventions were analyzed when they assessed symptoms or quality of life in patients with schizophrenia. Cognitive function, social function, hospitalization, and safety were defined as secondary outcomes. Risk of bias was assessed using the risk of bias tool recommended by the Cochrane Back Review Group. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated.ResultsFive RCTs with a total of 337 patients were included; 2 RCTs had low risk of bias. Two RCTs compared yoga to usual care; 1 RCT compared yoga to exercise; and 2 3-arm RCTs compared yoga to usual care and exercise. No evidence was found for short-term effects of yoga compared to usual care on positive symptoms (SMD = -0.58; 95% CI -1.52 to 0.37; P = 0.23), or negative symptoms (SMD = -0.59; 95% CI -1.87 to 0.69; P = 0.36). Moderate evidence was found for short-term effects on quality of life compared to usual care (SMD = 2.28; 95% CI 0.42 to 4.14; P = 0.02). These effects were only present in studies with high risk of bias. No evidence was found for short-term effects on social function (SMD = 1.20; 95% CI -0.78 to 3.18; P = 0.23). Comparing yoga to exercise, no evidence was found for short-term effects on positive symptoms (SMD = -0.35; 95% CI -0.75 to 0.05; P = 0.09), negative symptoms (SMD = -0.28; 95% CI -1.42 to 0.86; P = 0.63), quality of life (SMD = 0.17; 95% CI -0.27 to 0.61; P = 0.45), or social function (SMD = 0.20; 95% CI -0.27 to 0.67; P = 0.41). Only 1 RCT reported adverse events.ConclusionsThis systematic review found only moderate evidence for short-term effects of yoga on quality of life. As these effects were not clearly distinguishable from bias and safety of the intervention was unclear, no recommendation can be made regarding yoga as a routine intervention for schizophrenia patients.

Heart failure is the end stage of all cardiovascular diseases, which brings a heavy burden to the global health network. Arotinolol, as a new type of β Receptor blocker, has a good antihypertensive effect. Many clinical trials have observed the clinical efficacy of arotinolol in the treatment of essential hypertension. However, so far, there has been no systematic evaluation on the efficacy and safety of arotinolol in the treatment of chronic heart failure. The purpose of this review was to systematically evaluate the clinical efficacy of arotinolol in patients with chronic heart failure. Randomized controlled trials (RCTs) of arotinolol in the treatment of chronic heart failure were retrieved from seven databases according to the Cochrane manual, including CNKI (China National Knowledge Infrastructure), Wan fang database, VIP database, PubMed, Sinomed, EMBASE, and the Cochrane Library databases. The main outcomes were the effective rate, left ventricular ejection fraction (LVEF), blood pressure, heart rate, cardiac index, stroke volume (SV), brain natriuretic peptide (BNP), hypersensitive C-reactive protein (Hs-CRP), left ventricular end diastolic volume (LVEDV), left ventricular end diastolic diameter (LVEDD), and adverse events (AEs). A total of 17 trials met the qualification criteria, which included 1,717 patients with heart failure. Most trials had uncertain risks in terms of random sequence generation, allocation hiding, patient loss, and result evaluation. Meta analysis showed that arotinolol significantly improved the treatment efficiency of patients with heart failure (standardized mean difference (SMD) = 4.07, 95% confidence interval (CI) [2.89, 5.72], p = 0.00, I 2 = 0), LVEF (SMD = 1.59, 95% CI [0.99, 2.19], p = 0.000 0, I 2 = 95.8%), cardiac index (SMD = 0.32, 95% CI [0.11, 0.53], p = 0.03), I 2 = 0), SV (SMD = 2.00, 95% CI [1.57, 2.34], p = 0.000, I 2 = 64.2%), lower BNP (SMD = -0.804, 95% CI [-0.97, -0.64], p = 0.000, I 2 = 94.4%), and LVEDV (SMD = -0.25, 95% CI [-0.45, -0.05], p = 0.015, I 2 = 0). There was no statistical significance for blood pressure (SMDsystolic pressure = -0.09, 95% CI [-0.69, 0.51], p = 0.775, I 2 systolic pressure = 90.2%; SMDdiastolic pressure = -0.16, 95% CI [-0.79, 0.48], P = 0.632, I 2 diastolic pressure = 91.2%), heart rate (SMD = -0.12, 95% CI [-1.00, 0.75], P = 0.787, I 2 = 96.1%), Hs-CRP (SMD = -1.52, 95% CI [-3.43, 0.40], P = 0.121, I 2 = 98.3%), and LVEDD (SMD = -0.07, 95% CI [-0.90, 0.76], P = 0.870, I 2 = 96.5%). Arotinolol can safely and effectively improve the effective rate of patients with chronic heart failure, increase LVEF, increase CI and SV, and reduce BNP and LVEDV. However, because of the low overall quality of the included randomized controlled trials, these findings need to be considered carefully. More high-quality randomized controlled trials are needed for further verification, to provide a more scientific basis for the safety and effectiveness of arotinolol in the clinical treatment of heart failure.

Background and Purpose- Warfarin is associated with a better net clinical benefit compared with no treatment in patients with nonvalvular atrial fibrillation (AF) and history of intracranial hemorrhage (ICH). There are limited data on nonvitamin K antagonist oral anticoagulants (NOACs) in these patients, especially in the Asian population. We aimed to compare the effectiveness and safety of NOACs to warfarin in a large-scale nationwide Asian population with AF and a history of ICH. Methods- Using the Korean Health Insurance Review and Assessment database from January 2010 to April 2018, we identified patients with oral anticoagulant naïve nonvalvular AF with a prior spontaneous ICH. For the comparisons, warfarin and NOAC groups were balanced using propensity score weighting. Ischemic stroke, ICH, composite outcome (ischemic stroke+ICH), fatal ischemic stroke, fatal ICH, death from composite outcome, and all-cause death were evaluated as clinical outcomes. Results- Among 5712 patients with AF with prior ICH, 2434 were treated with warfarin and 3278 were treated with NOAC. Baseline characteristics were well-balanced after propensity score weighting (mean age 72.5 years and CHA2DS2-VASc score 4.0). Compared with warfarin, NOAC was associated with lower risks of ischemic stroke (hazard ratio [HR], 0.77 [95% CI, 0.61-0.97]), ICH (HR, 0.66 [95% CI, 0.47-0.92]), and composite outcome (HR, 0.73 [95% CI, 0.60-0.88]). NOAC was associated with lower risks of fatal stroke (HR, 0.54 [95% CI, 0.32-0.89]), death from composite outcome (HR, 0.53 [95% CI, 0.34-0.81]), and all-cause death (HR, 0.83 [95% CI, 0.69-0.99]) than warfarin. NOAC showed nonsignificant trends toward to reduce fatal ICH compared with warfarin (HR, 0.47 [95% CI, 0.20-1.03]). Conclusions- NOAC was associated with a significant lower risk of ICH and ischemic stroke compared with warfarin. NOAC might be a more effective and safer treatment option for Asian patients with nonvalvular AF and a prior history of ICH.

Psychological therapies for the management of chronic pain (excluding headache) in adults.

ObjectivesTo systematically assess the evidence of Craniosacral Therapy (CST) for the treatment of chronic pain.MethodsPubMed, Central, Scopus, PsycInfo and Cinahl were searched up to August 2018. Randomized controlled trials (RCTs) assessing the effects of CST in chronic pain patients were eligible. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for pain intensity and functional disability (primary outcomes) using Hedges’ correction for small samples. Secondary outcomes included physical/mental quality of life, global improvement, and safety. Risk of bias was assessed using the Cochrane tool.ResultsTen RCTs of 681 patients with neck and back pain, migraine, headache, fibromyalgia, epicondylitis, and pelvic girdle pain were included. CST showed greater post intervention effects on: pain intensity (SMD = -0.32, 95%CI = [− 0.61,-0.02]) and disability (SMD = -0.58, 95%CI = [− 0.92,-0.24]) compared to treatment as usual; on pain intensity (SMD = -0.63, 95%CI = [− 0.90,-0.37]) and disability (SMD = -0.54, 95%CI = [− 0.81,-0.28]) compared to manual/non-manual sham; and on pain intensity (SMD = -0.53, 95%CI = [− 0.89,-0.16]) and disability (SMD = -0.58, 95%CI = [− 0.95,-0.21]) compared to active manual treatments. At six months, CST showed greater effects on pain intensity (SMD = -0.59, 95%CI = [− 0.99,-0.19]) and disability (SMD = -0.53, 95%CI = [− 0.87,-0.19]) versus sham. Secondary outcomes were all significantly more improved in CST patients than in other groups, except for six-month mental quality of life versus sham. Sensitivity analyses revealed robust effects of CST against most risk of bias domains. Five of the 10 RCTs reported safety data. No serious adverse events occurred. Minor adverse events were equally distributed between the groups.DiscussionIn patients with chronic pain, this meta-analysis suggests significant and robust effects of CST on pain and function lasting up to six months. More RCTs strictly following CONSORT are needed to further corroborate the effects and safety of CST on chronic pain.Protocol registration at ProsperoCRD42018111975.

Background and Aims Hyperphosphatemia is a serious complication in chronic kidney disease (CKD) patients that serves as the main risk factor of CKD–mineral and bone disorder (CKD-MBD) progression. Previous studies suggested that iron-based phosphate binder showed better improvement in CKD-MBD parameters although the results were still inconclusive. This study aims to juxtapose the efficacies between iron-based and non-calcium phosphate binders for improving CKD-MBD parameters in dialysis-dependent (DD)-CKD patients. Method We did comprehensive searching to screen all relevant literature until November 2020 in online databases of Pubmed, EMBASE, ScienceDirect, and The Cochrane Library. We included all randomized controlled trials (RCTs) accessing the efficacies of iron-based phosphate binders (sucroferric oxyhydroxide, ferric citrate) in improving CKD-MBD parameters compared with non-calcium phosphate binders (sevelamer) in DD-CKD patients. The parameters compared in this study are changes in serum phosphate (P), serum calcium ions (Ca), fibroblast growth factors-23 (FGF23), intact parathyroid hormone (iPTH), 25-hydroxyvitamin D (calcidiol), and 1,25-dihydroxyvitamin D (calcitriol). Bias risk was accessed by using the revised Cochrane Risk-of-bias (RoB-2) tool. Analysis was performed to provide standard mean difference (SMD) with 95% confidence interval (CI) using random-effect heterogeneity test. Results Ten RCTs with total of 1,139 participants were included in this analysis. The sucroferric oxyhydroxide decreases FGF23 although not statistically significant (SMD = 0.22. 95% CI = -0.49 to 0.05, p = 0.11, I2 = 52%), but ferric citrate (SMD = -0.92. 95%CI = -1.56 to -0.29, p = 0.004, I2 = 69%) and the overall estimate (SMD = -0.45. 95% CI = -0.82 to -0.09, p = 0.02, I2 = 79%) showed significant FGF23 decline compared with sevelamer. The sucroferric oxyhydroxide showed no significant improvement of calcidiol (SMD = 0.08. 95%CI = -0.02 to 0.17, p = 0.13, I2 = 0%) and calcitriol (SMD = 0.02. 95% CI = -0.08 to 0.12, p = 0.74, I2 = 0%) compared with selevamer. There is also no significant improvement of iPTH in sucroferric oxyhydroxide subgroup (SMD = -0.14. 95%CI = -0.43 to 0.14, p = 0.32, I2 = 85%), ferric citrate subgroup (SMD = -0.02. 95%CI = -0.16 to 0.12, p = 0.80, I2 = 0%), and pooled group analysis (SMD = -0.10. 95%CI = -0.27 to 0.07, p = 0.27, I2 = 75%). Besides, this study also suggests no significant improvement comparison of serum P (SMD = -0.09. 95%CI = -0.19 to 0.02, p = 0.12, I2 = 38%) and Ca (SMD = 0.04. 95%CI = -0.12 to 0.20, p = 0.61, I2 = 57%). Conclusion There is no significant efficacies differences between iron-based and non-calcium phosphate binders for improving serum phosphate, serum calcium ions, iPTH, calcidiol, and calcitriol in dialysis-dependent chronic kidney disease patients, except for the FGF-23 parameter. However, further trials are needed to establish the juxtaposition.
