Background No network meta‐analysis has considered the relative efficacy of cilostazol, home exercise therapy, supervised exercise therapy (SET), endovascular revascularization (ER), and ER plus SET (ER+SET) in improving maximum walking distance (MWD) over short‐ (<1 year), moderate‐ (1 to <2 years), and long‐term (≥2 years) follow‐up in people with intermittent claudication. Methods and Results A systematic literature search was performed to identify randomized controlled trials testing 1 or more of these 5 treatments according to Preferred Reporting Items for Systematic Review and Meta‐Analysis guidelines. The primary outcome was improvement in MWD assessed by a standardized treadmill test. Secondary outcomes were adverse events and health‐related quality of life. Network meta‐analysis was performed using the gemtc R statistical package. The Cochrane collaborative tool was used to assess risk of bias. Forty‐six trials involving 4256 patients were included. At short‐term follow‐up, home exercise therapy (mean difference [MD], 89.4 m; 95% credible interval [CrI], 20.9–157.7), SET (MD, 186.8 m; 95% CrI, 136.4–237.6), and ER+SET (MD, 326.3 m; 95% CrI, 222.6–430.6), but not ER (MD, 82.5 m; 95% CrI, −2.4 to 168.2) and cilostazol (MD, 71.1 m; 95% CrI, −24.6 to 167.9), significantly improved MWD (in meters) compared with controls. At moderate‐term follow‐up, SET (MD, 201.1; 95% CrI, 89.8–318.3) and ER+SET (MD, 368.5; 95% CrI, 195.3–546.9), but not home exercise therapy (MD, 99.4; 95% CrI, −174.0 to 374.9) or ER (MD, 84.2; 95% CrI, −35.3 to 206.4), significantly improved MWD (in meters) compared to controls. At long‐term follow‐up, none of the tested treatments significantly improved MWD compared to controls. Adverse events and quality of life were reported inconsistently and could not be meta‐analyzed. Risk of bias was low, moderate, and high in 4, 24, and 18 trials respectively. Conclusions This network meta‐analysis suggested that SET and ER+SET are effective at improving MWD over the moderate term (<2 year) but not beyond this. Durable treatments for intermittent claudication are needed.

Background: The aim of our study was to synthesize evidence on the occurrence of malignancy in spondyloarthritis (SpA), from randomized controlled trials (RCTs) comparing biologics with non-biologics and biologics to each other. Methods: We systematically searched Medline, Cochrane Library, EMBASE, Scopus and ClinicalTrials.gov from inception until 31 October 2018. RCTs with ⩾24-week follow-up were included. We extracted data using standardized forms and assessed the risk of bias using the Cochrane Risk of Bias Tool. We performed pair-wise meta-analyses and network meta-analyses to compare the risk of malignancy for each biologics class and SpA type. We reported the Peto odds ratio (OR) of any malignancy along with 95% confidence intervals (95% CI). Bayesian posterior probabilities comparing risk of malignancy of each biologic class with non-biologics were computed as supplementary measures. Results: Fifty-four trials were included; most (44/54) had follow-up <1 year. Among 14,245 patients, 63 developed a malignancy. While most Peto ORs were >1, they had wide 95% CI and p >0.05. The overall Peto OR comparing biologics with non-biologics was 1.42 (95% CI 0.80–2.53). Only interleukin-17 inhibitors in peripheral SpA had p <0.05 (Peto OR 2.77, 95% CI 1.07–7.13); the posterior probability that the risk was higher than non-biologics was 98%. Stratified analyses revealed no consistent trend by prior exposure to biologics, duration of follow-up, study quality, study-arm crossover, analytical approaches and type of malignancy. Conclusions: Our findings indicate no overall elevated risk of malignancy with biologics in SpA. As our meta-analyses are unable to conclude on the long-term risk, long-term pharmacovigilance of biologics in SpA may still be warranted.

Abstract Background We performed an updated systematic review and meta-analysis which enrolled 25 prospective randomized controlled trials (RCTs) to compare the outcomes between total hip arthroplasty (THA) and hemiarthroplasty (HA) in patients with femoral neck fractures (FNFs). Methods We searched English databases which included PubMed, Embase (vis OvidSP), The Cochrane Library, and Web of Science, and Chinese databases Chinese National Knowledge Infrastructure (CNKI), VIP, Wang Fang, and China Biology Medicine Disc (CBM) in July 2020. The quality of each study was assessed according to the Cochrane Collaboration’s Risk of Bias. Risk ratios (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were pooled with random-effects models. Data regarding baseline characteristics, hospital and surgery outcomes, clinical outcomes, patients’ quality of life, common complications, prothesis-related complications, mortality, and costs were reported. Results A total of 25 RCTs involving 3223 patients (1568 THA and 1655 HA) were included. THA had longer hospital length (WMD = 0.721, P < 0.0001) and surgery time (WMD = 20.044, P < 0.0001), and more blood loss compared with HA (WMD = 69.109, P < 0.0001). THA showed better ratings in the Harris Hip Score during follow-up periods between 1 and 5 years while no differences within 6 months and after 9 years. THA was associated with higher quality-of-life EuroQol-5 Dimension (EQ-5D) scores after 2 years of surgery but no difference within 1 year. There was no difference in common complications. THA had significant higher rate of dislocation (WMD = 1.897, P = 0.002) and lower acetabular erosion (WMD = 0.030, P = 0.001). For mortality, there was no difference during all the follow-up periods except for slightly higher 2-year mortality after surgery. Conclusion This meta-analysis demonstrates that THA has better medium-term functional results and quality of life and lower acetabular erosion rate, while HA shows better in reducing hospital stay, surgery time, and blood loss and also has lower dislocation rate.

Objective. Heart failure is a major public health problem worldwide nowadays. However, the morbidity, mortality, and awareness of heart failure are not satisfied as well as the status of current treatments. According to the standard treatment for chronic heart failure (CHFST), Fuzi (the seminal root of Aconitum carmichaelii Debx.) formulae are widely used as a complementary treatment for heart failure in clinical practice for a long time. We are aiming to assess the efficacy and safety of Fuzi formulae (FZF) on the treatment of heart failure according to high-quality randomized controlled trials (RCTs). Methods. RCTs in PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP), and Wanfang Database were searched from their inception until June 2019. In addition, the U.S. National Library of Medicine (clinicaltrials.gov) and the Chinese Clinical Trial Registry (http://www.chictr.org.cn) were also searched. We included RCTs that test the efficacy and safety of FZF for the treatment of heart failure, compared with placebo, CHFST, or placebo plus CHFST. The methodological quality of included studies were evaluated by the Cochrane Collaboration’s tool for assessing risk of bias. RCTs with Cochrane risk of bias (RoB) score ≥4 were included in the analysis. The meta-analysis was conducted through RevMan 5.2 software. The GRADE approach was used to assess the quality of the evidence. Results. Twelve RCTs with 1490 participants were identified. The studies investigated the efficacy and safety of FZF, such as FZF plus the CHFST vs placebo plus CHFST (n = 4), FZF plus CHFST vs CHFST (n = 6), FZF plus digoxin tablets (DT) plus CHFST vs placebo plus DT plus CHFST (n = 1), and FZF plus placebo plus CHFST vs placebo plus DT plus CHFST (n = 1). Meta-analysis indicated that FZF have additional benefits based on the CHFST in reducing plasma NT-proBNP level, MLHFQ scores, Lee’s heart failure scores (LHFs), and composite cardiac events (CCEs). Meanwhile, it also improved the efficacy on TCM symptoms (TCMs), NYHA functional classification (NYHAfc), 6MWD, and LVEF. Adverse events were reported in 6 out of 12 studies without significant statistical difference. However, after assessing the strength of evidence, it was found that only the quality of evidence for CCEs was high, and the others were either moderate or low or very low. So we could not draw confirmative conclusions on its additional benefits except CCEs. Further clinical trials should be well designed to avoid the issues that were identified in this study. Conclusion. The efficacy and additional benefits of FZF for CCEs were certain according to the high-quality evidence assessed through GRADE. However, the efficacy and additional benefits for the other outcomes were uncertain judging from current studies. In addition, the safety assessment has a great room for improvement. Thus, further research studies are needed to find more convincing proofs.

Abstract Background: The efficacy of traditional Chinese medicine injections (TCMIs) for angina pectoris has never been well investigated for lacking quality assessment of evidence. This study aimed to conduct a comprehensive and rigorous network meta-analysis and assess the quality of evidence according to the Grading of Recommendations and Assessment, Development, and Evaluation (GRADE) approach to compare the efficacy of all TCMIs in treating angina pectoris.Methods: Following the protocol (reference: CRD42018117720), randomized controlled trials (RCTs) which compared one TCMI with another TCMI or conventional treatments on anginal outcome measures (i.e. symptomatic improvement, electrocardiography improvement, symptomatic recovery, and electrocardiography recovery) were included. The risk of bias among included RCTs was assessed with the revised Cochrane’s risk of bias tool 2. Frequentist statistical analyses including subgroup analysis, sensitivity analysis, meta-regression and publication bias analysis were performed. The certainty of evidence was assessed with the GRADE approach.Results: Totally, 475 RCTs including all 24 TCMIs were identified, while the quality of all but two included RCTs was poor. According to the network meta-analysis, Honghua (Safflower) injection were preferable both in improving symptoms and electrocardiography. However, significant inconsistency showed the intransitivity among indirect comparisons, results in network meta-analysis seemed thus not trustworthy. The quality of evidence was assessed as low or very low.Conclusions: The low-quality evidence reduced the confidence in the efficacious results. Current evidence hardly supports the beneficial effects of TCMIs in treating angina pectoris.

Introduction: Female sexual dysfunction is a common problem, affecting more than 1/3 of women during their lives. The aim of this review is to review the evidence for the effectiveness of testosterone in sexual dysfunction in postmenopausal women, particularly in the improvement of sexual desire.Material and Methods: The authors searched in international databases National Guidelines Clearinghouse, Guidelines Finder, Cochrane Library and MEDLINE/PubMed, for guidelines, systematic reviews, meta-analysis and randomized controlled trials, published between January 2005 and February 2017, using the MeSH terms ‘testosterone’, ‘androgens’, ‘libido’, ‘sexual dysfunctions’ and ‘menopause’.Results: From a pool of 506 articles, 11 were selected: three guidelines, one systematic review with meta-analysis and seven randomized controlled trials. The selected articles showed testosterone‘s efficacy on global sexual function and improvement of sexual desire in postmenopausal women, when both are used in monotherapy or in association with other hormones. No study showed changes in hepatic enzymes or serious adverse effects.Discussion: The small sample size and short follow-up used in the included studies limits the ability to assess testosterone’s long-term benefits and effects.Conclusion: At short-term, testosterone seems to improve sexual function in postmenopausal women, particularly sexual desire. Nevertheless, more studies with larger sample size and longer follow-up are needed to understand its long-term safety and effectiveness.

Background:Knee osteoarthritis (OA) is a frequent degenerative disease representing an important health and economic burden. Symptomatic medical treatments available include intra-articular (IA) injections of corticosteroids (GC) but their efficacy is debated. In addition, safety signals regarding cartilage damage with IA GC have been highlighted in a few studies.Objectives:To perform a meta-analysis of studies assessing IA GC efficacy and safety in knee OA.Methods:A systematic literature review and a meta-analysis of randomized controlled trials (RCTs) assessing the effect of GC IA injections versus other interventions (IA Hyaluronic Acid, IA placebo, IA NSAID, oral NSAID or physiotherapy) in knee OA was performed. The effect of the interventions on pain and function were extracted from the single studies and pooled and are presented as short term (<6weeks), medium term (6-24 weeks) and long term (>24 weeks) follow-up period. Standardized mean differences (SMD) are reported.Results:Of 520 studies screened, 23 were included in the SLR and 14 subsequently included in the MA. While IA GC showed a superior effect compared to control on both pain (SMD -0.61 (95% CI -1,25, 0.03)) and function (SMD -1.02 (95% CI -2.14, 0.10)) in short term follow-up; long term follow-up analysis favored controls (IA HA, IA NSAID, physiotherapy) for both pain (SMD 0.68 (95% CI -0.11, 1.47)) and function (SMD 0.88 (95% CI -0.36, 2.12) outcomes (Figure 1). No difference was found between interventions in the medium term. Safety data were reported in 18/23 studies (n= 1936/2314 patients); and side effects were reported as follows: arthralgia (69 IA GC patients, 146 IA HA patients, and 20 saline patients); site injection pain (7 in the IA GC group, 2 in the IA saline group, 14 in the IA HA group); 16 post injection knee swelling without signs of septic arthritis in the IA GC group and 24 in the IA HA group. In one study assessing cartilage effects of GCs, the rate of cartilage loss was greater in the GC group with a reduction of cartilage thickness at 2 year compared to placebo group. No difference was observed in the progression of cartilage denudation or bone marrow lesion. On the contrary, another study showed no effect of injections on the cartilage structure.Conclusion:We demonstrate in this work that IA GC injections reduce pain and improve function in the early phase (≤6 weeks) of treatment. In the long term (≥24 weeks), other intervention such as IA HA injections or physiotherapy seem to be more efficient, but this effect was largely driven by single studies with large effect sizes and the comparators were heterogeneous.Figure 1.Knee pain outcome at short term (≤6weeks) (A), medium term (>6 & <24 weeks) (B), and long term (≥24 weeks) (C) follow up.Disclosure of Interests:None declared.

Abstract Background Exercise therapy (aerobic or resistance therapy) could have a beneficial effect on balance, walking and quality of life (QoL). Objective This systematic review and meta-analysis aimed to quantify the effects of different modes, dosages and setting of exercise therapy on balance, walking capacity and QoL in stroke survivors. Methods We searched PubMed, CINHAL and Hinari to identify randomized controlled trials (RCT) that investigated the effects of aerobic (AT) and/or resistance therapy (RT) on balance, walking and QoL in stroke survivors. The treatment effect was computed by the standard mean differences (SMDs). Results We included 27 RCT comprising 1,549 chronic stroke survivors. Any modality was effective to improve balance. There was high-level evidence that AT interventions were most effective in improving walking capacity (SMD=0.36 [0.06, 0.66], p=0.02). Both AT, and AT combined with RT were effective to improve QoL (SMD=0.39 [0.09, 0.69], p=0.01). RT programs were not effective to improve walking and QoL. For walking capacity, a lower volume weekly (&lt;60 minutes/session or &lt;3 session/week) and higher intensity (&gt;60% heart rate reserve; rate of perceived exertion (6–20) &gt;14) of AT and RT exercises demonstrated significant higher effect. Hospital located rehabilitation settings trended to improve walking (SMD=0.23 [0.00, 0.45], p=0.05), when compared to home/community and laboratory settings. Conclusions In chronic stroke, in particular AT executed in hospital located settings, with a lower volume and high intensity seems more effective strategy to facilitate walking capacity and improve QoL and should thus be incorporated into rehabilitation programs for stroke.
