[Domain Type] Required Consistency is the degree to which included studies find either the same direction or similar magnitude of effect. The EPC can assess this through two main elements: Direction of effect: Effect sizes have the same sign (that is, are on the same side of no effect or a minimally important difference [MID]). Magnitude of effect: The range of effect sizes is similar. The EPC may consider the overlap of CIs when making this evaluation. The importance of direction vs. magnitude of effect will depend on the key question and EPC judgments. [Domain Score and Application] Score as one of three levels: Consistent Inconsistent Unknown (e.g., single study) Single-study evidence bases (including mega-trials) cannot be judged with respect to consistency. In that instance, use “Consistency unknown (single study).” [Domain Name]
