PrEP-related behavioral determinants from baseline to follow-ups, test for trend, and observed effect sizes.
Note 1. Difference test of paired data (mean changes between baseline and each follow-up assessment) using Wilcoxon signed-rank test. 2. Difference test of unmatched data (net changes from baseline to each follow-up assessment) using Wilcoxon rank-sum test. 3. Cohen’s d compares the difference of net changes of outcome variables from baseline to each follow-up between two arms. 5. Violation of normality (Shapiro-Wilk test). 6. Violation of homogeneity (variance-comparison test)The observed effect sizes measured by Cohen’s d (
