Abstract

GRADE and other Evidence to Decision (EtD) frameworks are widely used by guideline development groups (GDG) and other decision-makers. When GDGs judge the magnitude of desirable and undesirable health outcomes on EtDs, they typically categorize them as trivial, small, moderate or large. However, generic judgment or decision thresholds (DTs) that could guide the user about such estimates of effect size or serve as references for interpretation of findings are not yet available. The objective of this study was to empirically derive DTs for EtD judgments about the magnitude of dichotomously assessed health benefits and harms.
