Systematic reviewis a type ofliterature reviewthat uses pre-defined strategies to minimize bias in the identification and analysis of data from original articles.1Data from studies with potential to answer the systematic review question are often used for mathematical calculations.1Narrative reviews repor...
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 ...
Study Quality and Bias Pooled estimates of lifetime and past month prevalence for cross-sectional studies were lower compared to estimates from RCT and cohort studies, respectively. However, these observations are inconclusive as there was only one RCT and one cohort study reported lifetime and pas...

Studies were selected based on the patient, intervention, comparator, and outcome criteria and assessed for the risk of bias using the Cochrane tool. Meta-analysis was conducted by pooling mean differences with 95% confidence intervals. Results A total of 14 RCTs, involving 524 participants, were...
The quality (0 to 1) of the studies was moderate, with a mean of 55% of quality criteria being met, suggesting some susceptibility to systematic bias may have existed. Hard stabilization appliances, when adjusted properly, have good evidence of modest efficacy in the treatment of TMJD pain ...
and synthesise the results of empirical studies that have (i) investigated the prevalence of selective inclusion or reporting in systematic reviews of RCTs, (ii) investigated the factors associated with this (e.g. statistical significance or direction of effect), and (iii) quantified the bias.关...
We searched the Cochrane Library and MEDLINE and evaluated systematic reviews that include at least one tRCT. We documented approaches that authors used to address potential overestimates of treatment effect introduced by including tRCTs. We assessed the impact of tRCTs in meta-analyses on the ...
Tools for assessing quality and susceptibility to bias in observational studies in epidemiology: a systematic review and annotated bibliography Assessing quality and susceptibility to bias is essential when interpreting primary research and conducting systematic reviews and meta-analyses. Tools for... S ...
Study selection, data extraction and data analysis steps were performed as described in previous editions of the authors’ living systematic review [8,9]. As all included studies were RCTs, RoB was assessed using the Cochrane Risk of Bias 2 tool [25]. Data analysis Results from individual stu...
