Some possible risks of bias due to sequence generation may exist due to non-, quasi-randomized methods of allocation. These methods may allow clinicians to choose which treatment patients’ will get within the study based on their expertize and prior experiences (i.e., A non-random factor)....
Our aims were to assess the reliability and usability of a new Cochrane risk of bias (RoB) tool for non-randomized studies of interventions and to determine whether restricting analysis to studies with low or moderate RoB made a material difference to the results of the reviews. We selected ...

Risk of bias The three studies were assessed using NOS and all were rated with 8 stars, which is considered as having a relatively high quality (selection of subjects, 4 stars; comparability of groups, 2 stars; assessment of outcome, 2 stars). Meta-analysis results In the meta-analysis of...
Performance bias due to knowledge of the allocated interventions by participants and personnel during the study. Detection bias Blinding of outcome assessment Assessments should be made for each main outcome (or class of outcomes) Describe all measures used, if any, to blind ...
In brief, a second meta-analysis including only studies identified as having a low risk of bias would be compared to the primary meta-analysis. A difference in the overall estimated effects between these 2 meta-analyses could suggest that biased results impacted the primary meta-analysis. However...
However, most reports did not include a description of the study population or intended use of the models and were rated at high risk of bias at the same time. Early detection of patients who are likely to develop critical illness is of great importance and may help to deliver proper care...
