Table 1 Criteria for an “incorrect answer” based on difference in statistical significance and magnitude of effect

From: Assessing the validity of abbreviated literature searches for rapid reviews: protocol of a non-inferiority and meta-epidemiologic study

Criteria for incorrect answer
Change in statistical significance Statistical significance changes between graded effect and gold standard effect (trivial changes in p values within the range of 0.04 to 0.06 are not considered as a change).
Change in magnitude of effect Difference in magnitude of effects is larger than a relative risk change (increase or reduction) of 25 percentage points for dichotomous outcomes or 0.20 SMDs for continuous outcomes.
