[Domain Type] Required Precision is the degree of certainty surrounding an effect estimate with respect to a given outcome, based on the sufficiency of sample size and number of events. Several caveats must be considered in determining the precision of a body of evidence. A body of evidence will generally be imprecise if the optimal information size (OIS) is not met. OIS refers to the minimum number of patients (and events when assessing dichotomous outcomes) needed for an evidence base to be considered adequately powered. If an EPC performed a meta-analysis, then it may also consider whether the CI crossed a threshold for an MID. If meta-analysis is infeasible or inappropriate, the EPC may consider the narrowness of the range of CIs or the significance level of p-values in the individual studies in the evidence base. [Domain Score and Application] Score as one of two levels: Precise Imprecise A precise estimate is one that would allow users to reach a clinically useful conclusion (e.g., treatment A is more effective than treatment B).
