aPost-pre intervention.
bFor example, 50 mg post-pre–200 mg post-pre.
cThe smallest worthwhile clinical change is 1%. The probability that a contrast was at least greater than the clinical threshold was 25–75% possible, 75–95% likely, 95–99.5% very likely, and >99.5% almost certain. The terms benefit, trivial, and harm also denoted by symbols ↑, ↔, and ↓, respectively, refer to the most likely directional outcome relative to the smallest effect threshold. Unclear refers to outcomes where the likelihood of both benefit and harm exceeded 5%. The clinical adoption threshold was expressed as a benefit: harm odds ratio >66 : 1.
