One review, focusing on body composition and weight loss, although systematic in its methods and including randomised controlled studies, drew similar conclusions, but by combining randomised and nonrandomised studies the protection against bias and confounding by randomisation was lost.
Research studies (no methodological restrictions case series, cohort, cross-sectional, non-randomised controlled, consensus method, case control and randomised controlled) and non-research study designs (editorial, guideline, letter to the editor and narrative review) are eligible.
Additional comparisons are also performed between the proposed AMALGAM method and a randomised (or no-learning) version thereof, as well as a selection choice function-based multiobjective hyperheuristic available in the literature.
Conclusion Peer reviewers fail to detect important deficiencies in reporting of the methods and results of randomised trials.
11 Importantly, despite some improvements in reporting after peer review, it is clear that peer reviewers often fail to detect several important deficiencies in the reporting of the methods and results of randomised trials.
21 Based on this sample of BMC-series medical journals, we found that peer reviewers failed to detect important deficiencies in the reporting of the methods and results in randomised trials.
Review methods We included randomised and quasi-randomised controlled trials of weaning from mechanical ventilation with and without protocols in critically ill adults.
In the field of health, evidence-based medicine and associated methods like randomised controlled trials (RCTs) have become widely used.
Statistical analysis will follow standard methods for randomised trials and the primary analysis will be by intention to treat.
