A methodological survey of the analysis reporting and interpretation of Absolute Risk ReductiOn in systematic revieWs (ARROW): a study protocol

摘要

BackgroundClinicians, providers and guideline panels use absolute effects to weigh the advantages and downsides of treatment alternatives. Relative measures have the potential to mislead readers. However, little is known about the reporting of absolute measures in systematic reviews. The objectives of our study are to determine the proportion of systematic reviews that report absolute measures of effect for the most important outcomes, and ascertain how they are analyzed, reported and interpreted.
