ObjectiveTo overview of systematic reviews (SRs) of Yiqi Fumai (YQFM) injection in the treatment of chronic heart failure (CHF). MethodsThe PubMed, Cochrane Library, EMbase, Web of Science, CNKI, CBM and WanFang Data databases were electronically searched to collect SRs of YQFM injection in the treatment of CHF from January 1, 2007 to October 31, 2022. Two reviewers independently screened literature, extracted data and assessed methodological quality, risk of bias, report quality and evidence quality by using AMSTAR-2, ROBIS scale, PRISMA, and GRADE system. ResultsA total of 7 SRs were included. The evaluation results showed that the quality of all SRs was low, a few SRs were assessed as having a low risk of bias, and all SRs were relatively completely reported. A total of 46 results were extracted from the included SRs, including 3 with moderate quality evidence, 12 with low quality evidence and 31 with very low quality evidence. ConclusionYQFM may be an effective and safe treatment, but current evidence quality is low.
ObjectivesTo conduct an overview of systematic reviews (SRs) on Tuina from 2013 to 2017, and to explore recent research improvements on Tuina.MethodsPubMed, Web of Science, The Cochrane Library, SpringerLink e-book database, CNKI, VIP, WanFang Data and CBM databases were searched to collect SRs including randomized controlled clinical trials on Tuina from January 1st, 2013 to December 31st, 2017. Two reviewers independently screened literature, extracted data, and used AMSTAR 2 tool and PRISMA statement to assess methodology quality and reporting quality of included studies, respectively. The R 3.4.3 software was used to analyze data.ResultsA total of 8 SRs studies were included in the overview. The studied diseases involved radiculopathy cervical spondylotic, myelopathy cervical spondylotic, constipation, child anorexia, child diarrhea and external humeral epicondylitis. The results of above SRs showed that massage might be superior to other interventions in clinical efficacy, curative effects or total effective rate. However, due to the low quality of included studies of SRs, further evidence from high-quality clinical studies is required to verify above conclusions. For the results of AMSTAR 2 assessment, all 8 SRs were rated as very low quality. The quantity of items accomplished for each SR ranged from 7 to 13, 2 SRs had low methodological quality (percentage of accomplishment or partial accomplishment <50.0%) and 6 SRs with high methodological quality (percentage of accomplishment or partial accomplishment ≥50.0%). All 8 SRs did not report item 2 "Whether to declare research methods", item 10 "Whether reports have included funding sources for each study" and item 11 "Whether reports used the correct statistical method". The results of PRISMA assessment showed that all SR had good quality of reporting. The accomplished items number of each SR ranged from 22 to 26. However, there were defects in item 5(0), item 16(25.0%) and item 23(25.0%). All SRs did not report item 5 "Whether to declare research program".ConclusionsThis study finds that Tuina has supportive evidence-based medical evidence for treating anorexia, cervical spondylosis and other diseases, however, the SRs of Tuina are yet needed to be improved in terms of standardized degree. Therefore, establishing a reporting consolidated standard for evidence-based medicine on Tuina in order to improve the quality of clinical studies so as to provide clinicians with high-quality evidence is the focus of our further research.
ObjectiveTo overview the systematic reviews on efficacy and safety of hyperbaric oxygen in treatment of diabetic foot.MethodsCNKI, CBM, VIP, WanFang Data, The Cochrane Library, PubMed and EMbase databases were searched to collect systematic reviews or meta-analyses on the efficacy and safety of hyperbaric oxygen therapy for diabetic foot from inception to November 17th, 2019. Two researchers independently screened literature and extracted data. Then, AMSTAR 2 tool and PRISMA statement were used to evaluate the methodological quality and reporting quality of included systematic reviews, and the outcome indicators were comprehensively analyzed.ResultsA total of 10 systematic reviews were included. The results of AMSTAR 2 suggested that 6 systematic reviews were of extremely low quality, 3 of low quality, and 1 of high quality. The PRISMA score ranged from 16.5 to 27. The results of the included systematic reviews showed that hyperbaric oxygen therapy might be superior to other interventions in ulcer healing rate and large amputation rate without increasing the risk of adverse events. ConclusionsThe existing systematic reviews/meta-analysis evidence shows that hyperbaric oxygen therapy may have certain curative effect on diabetic foot, however, its methodology and report quality evaluation are insufficient.
ObjectiveTo conduct an overview of systematic reviews on the impact of evidence-based learning (EBL) method on medical education. MethodsThe CNKI, WanFang Data, VIP, CBM, PubMed, Embase, Cochrane Library, and Web of Science databases were electronically searched to collect the relevant systematic reviews or meta-analyses of the application of EBL method in medical education from inception to May, 2024. Two researchers conducted the literature screening and data extraction independently. The AMSTAR 2, ROBIS tool, PRISMA 2020, and GRADE system were separately used to evaluate the methodological quality, the risk of bias, the quality of reporting, and the quality of evidence of included studies. ResultsA total of 16 systematic reviews/meta-analyses were included. The methodological quality evaluation by AMSTAR 2 showed that the quality level of 16 studies was very low. The results of ROBIS tool showed that 1 study was low risk of bias and 15 studies were high risk of bias. The GRADE evaluation of the evidence quality for 36 outcome indicators in the included studies revealed that 6 were of moderate quality, 12 were of low quality, and the rest were of very low quality. ConclusionEBL method has demonstrated significant effects in improving theoretical performance, practical skills, and critical thinking abilities among medical students. However, the methodological and evidence quality of the current systematic reviews/meta-analyses are low.
Objectives To overview the systematic reviews/meta-analyses of safety of femoral nerve block (FNB) used as a postoperative analgesic technique in patients undergoing total knee arthroplasty (TKA). Methods We searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data, and VIP from inception to July, 2016. Two reviewers independently screened literature, extracted data and used AMSTAR to evaluate the methodological quality of the included studies. The major indexes used to evaluate the safety of FNB were the incidence rates of symptoms including nausea, vomiting, sedation, retention of urine, dizziness, pruritus, hypotension, falls, nenous thromboembolism and deep infection. Results A total of 12 systematic reviews/meta-analyses were included.They assessed the safety of FNB compared with local infiltration analgesia (LIA), periarticular multimodal drug injection (PMDI), epidural analgesia (EA), patient-controlled intravenous analgesia of opioids (PCA) and adductor canal block (ACB), respectively. The methodological quality of included studies were medium, with the scores between 3 to 10. The results of overview indicated that: FNB had lower incidence rates of nausea and vomiting compared with EA and PCA, but had higher than ACB. FNB had lower incidence rates of sedation and retention of urine compared with EA and PCA. FNB had lower incidence rates of dizziness compared with EA and PCA, and lower incidence rate of hypotension compared with EA. Conclusion Current evidence suggests that FNB is safer than EA and PCA. Due to the limited quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
ObjectiveTo evaluate the quality of methodology and evidence of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture therapy for bronchial asthma. MethodsCNKI, CBM, VIP, WanFang Data, PubMed, The Cochrane Library and Web of Science databases were electronically searched to collect SRs/MAs of acupuncture therapy for bronchial asthma from inception to October 31, 2021. Four reviewers independently screened literature, extracted data, and applied the AMSTAR 2 to evaluate the quality of methodology of the included studies and the GRADE system to assess the certainty of evidence for outcomes. ResultsA total of 14 SRs/MAs were included and their main conclusions were that acupuncture therapy was beneficial in improving the clinical efficacy of bronchial asthma treatment. The evaluation of AMSTAR 2 showed that the methodological quality of all studies was all extremely low. The evidence grading of GRADE system showed that, in the total of 59 outcomes, 7 were graded as medium-level, 24 as low-level, 28 as extremely low-level, and none was graded as high-level. ConclusionThe current evidence shows the advantages of acupuncture therapy for bronchial asthma but the reliability of SRs/MAs is low. High-quality clinical studies are still needed to verify the efficacy of acupuncture therapy for bronchial asthma.
ObjectiveTo evaluate the risk of bias and reliability of conclusions of systematic reviews (SRs) of lung cancer screening. MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 2, 2016), Web of Knowledge, CBM, WanFang Data and CNKI to collect SRs of lung cancer screening from inception to February 29th, 2016. The ROBIS tool was applied to assess the risk of bias of included SRs, and then GRADE system was used for evidence quality assessment of outcomes of SRs. ResultsA total of 11 SRs involving 5 outcomes (mortality, detection rate, survival rate, over-diagnosis and potential benefits and harms) were included. The results of risk of bias assessment by ROBIS tool showed:Two studies completely matched the 4 questions of phase 1. In the phase 2, 6 studies were low risk of bias in the including criteria field; 8 studies were low risk of bias in the literature search and screening field; 3 studies were low risk of bias in the data abstraction and quality assessment field; and 5 studies were low risk of bias in the data synthesis field. In the phase 3 of comprehensive risk of bias results, 5 studies were low risk. The results of evidence quality assessment by GRADE system showed:three studies had A level evidence on the outcome of mortality; 1 study had A level evidence on detection; 1 study had A level evidence on survival rate; 3 studies on over-diagnosis had C level evidence; and 2 studies on potential benefits and harms had B level evidence. ConclusionThe risk of bias of SRs of lung cancer screening is totally modest; however, the evidence quality of outcomes of these SRs is totally low. Clinicians should cautiously use these evidence to make decision based on local situation.
ObjectiveTo overview the systematic reviews of the efficacy of cancer patient decision aids (PDAs) for treatment decision-making. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CINAHL, JBI, CNKI, VIP, CBM and WanFang Data databases were electronically searched to collect the systematic reviews relevant to the objective from inception to September 2023. Literature screening, data extraction, methodological quality assessment of the included literature, and summary and grading of the evidence were carried out independently by two researchers, and duplication of original studies in the included systematic evaluations was investigated using the corrected covered area (CCA). ResultsA total of 17 systematic reviews were included, of which 13 (76.47%) were low- or very low-quality studies. A total of 64 pieces of evidence were included, of which only 26 (40.62%) were of moderate quality, and the original studies included in the included literature had a low degree of overlap (CCA=0.05). The results of meta-analysis showed that PDAs could increase decision-related knowledge, reduce decision conflict and regret in cancer patients' treatment decision (P<0.05). However, there was no significant difference in decision satisfaction, anxiety or depression (P>0.05). ConclusionPDAs can improve cancer patients' knowledge related to treatment decision, reduce decision conflicts and regrets, and have no significant negative effects on decision preparation, satisfaction, anxiety, and depression. However, the existing systematic reviews are of low quality and limited to a few cancer types.
ObjectivesTo evaluate the quality of methodology and evidence of the exiting systematic reviews (SRs) of acupuncture therapy for post-stroke spastic paralysis.MethodsCNKI, CBM, The Cochrane Library, PubMed and EMbase databases were electronically searched to collect SRs of acupuncture therapy for post-stroke spastic paralysis from inception to December 16th, 2018. Two reviewers independently screened literature, extracted data, and evaluated the quality of methodology and evidence by AMSTAR 2 scale and GRADE system.ResultsA total of 7 SRs were included. The results showed that acupuncture therapy had obvious advantages in treating post-stroke spastic paralysis without obvious adverse reactions. The results of AMSTAR 2 scale showed that the failure of key items 2 and 7 resulted in extremely low methodological quality. The results of GRADE system showed that 46.15% of which were low-level evidence quality, 42.31% were medium, 11.54% were extremely low, and no evidence quality were high.ConclusionsCurrent evidence shows that acupuncture and moxibustion therapy is effective in treating spastic paralysis after stroke, however, the quality of the SRs is low. The studies are required to be standardized and combined with the characteristics of TCM to obtain high quality evidence in the future.
ObjectiveTo summarize and evaluate the quality of methodology, report and evidence of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture and moxibustion interventions for Parkinson's disease. MethodsEight databases including CNKI, WanFang Data, VIP, CBM, PubMed, EMbase, Cochrane Library and Web of Science were searched from inception to May 1, 2023. The quality of methodology, report and evidence involved in these studies were evaluated by AMSTAR 2, PRISMA and GRADE tool. ResultsA total of 28 SRs/MAs were included, and the findings of included studies showed that acupuncture and moxibustion had a clinical advantage for Parkinson's disease. The methodological quality of all studies was extremely low. Thirteen reports were relatively complete, 14 reports had certain flaws, and 1 report had relatively serious flaws. And of the 126 reports for seven outcomes, 1 was graded as high, 12 as moderate, 57 as low, and 56 as critically low. ConclusionThe current evidence shows that acupuncture and moxibustion have a certain clinical effect for Parkinson's disease, but the methodological quality and evidence quality of related SRs/MAs are low, and the standardization still needs to be improved. The efficacy of acupuncture and moxibustion in Parkinson's disease still needs to be verified by high-quality clinical studies in the future.
