[Domain Type] Required Reporting bias results from selectively publishing or reporting research findings bases on the favorability of direction or magnitude of effect. It includes: Study publication bias (i.e., nonreporting of the full study) Selective outcome reporting bias (i.e., nonreporting or incomplete reporting of unplanned outcomes) Selective analysis reporting bias (i.e., reporting of one or more favorable analyses for a given outcome while not reporting other, less favorable analyses. Assessment of reporting bias for individual studies depends on many factors including availability of study protocols, unpublished study documents, and patient-level data. Detecting such bias is likely with access to all relevant documentation and data pertaining to a journal publication, but such access is rare. Because methods to detect reporting bias in observational studies are less certain, this guidance does not require EPCs to assess it for such studies. [Domain Score and Application] Score as one of two levels: Suspected Undetected Reporting bias is suspected when: Testing for funnel plot asymmetry demonstrates a substantial likelihood of bias, and/or A qualitative assessment suggests the likelihood of missing studies, analyses, or outcomes data that may alter the conclusions from the reported evidence. Undetected reporting bias includes all alternative scenarios. [Domain Name]
