Assessment of risk of bias is regarded as an essential component of a systematic review on the effects of an intervention. The most commonly used tool for randomised trials is the Cochrane risk-of-bias tool. We updated the tool to respond to developments in understanding how bias arises in ra...
Methods Study design A cross-sectional design was employed. Any RCT that had been included in more than one Cochrane review of hypertension was identified. For each domain of the RoB tool, the level of agreement and disagreement between different reviews was assessed. Data sources We exported all...
Background: The Cochrane risk of bias (CROB) tool and Physiotherapy Evidence Database (PEDro) scale are used to evaluate risk of bias of randomized controlled trials. We assessed the level of agreement between the instruments. Methods: We searched the Cochrane Library to identify trials included ...
Methodological quality (risk of bias) assessment is an important step before study initiation usage. Therefore, accurately judging study type is the first priority, and the choosing proper tool is also important. In this review, we introduced methodologi
The Cochrane risk of bias tool for randomized clinical trials was introduced in 2008 and has frequently been commented on and used in systematic reviews. We wanted to evaluate the tool by reviewing published comments on its strengths and challenges and by describing and analysing how the tool is...
The Cochrane RoB tool highlighted a wide range of risks of bias in studies included in two widely cited reviews and had the potential to change the conclusions of the reviews. Systematic reviews that incorporate non-randomized studies of medical interventions should include a detailed assessment of ...
The RoB 2.0 tool con- sists of five bias domains and shows major changes when compared to the original Cochrane RoB tool (Table S1A-B presents major items of both versions). The Physiotherapy Evidence Database (PEDro) scale is a specialized methodological assessment tool for RCT in ...
Background In 2008, the Cochrane Collaboration introduced a tool for assessing the risk of bias in clinical trials included in Cochrane reviews. The risk of bias (RoB) tool is based on narrative descriptions of evidence-based methodological features known to increase the risk of bias in trials....
The Critical Appraisal of Methodological (technical) Quality, Quality of Reporting and Risk of Bias in Animal Research (CRIME-Q) tool unifies a broad spectrum of information (both unique items and items inspired by other methods) about the quality of reporting and methodological (technical) quality...
