| Proportion of Condom Use for Vaginal Sex [Median (Q1, Q3)] (n=66) | 1.0 (0.3, 1) | 0.92 (0.5, 1) | 1.0 (0.28, 1) | 0.8538 | 0.001 |

Note: SD=standard deviation; Q1=lower quartile; Q3=upper quartile.
P-values based on two-sample t-tests or Wilcoxon rank-sum tests for continuous variables, as appropriate; Fisher’s exact tests was used for categorical variables with cells containing less than 5 participants, and chi-square tests for all other categorical variables.
Effect sizes based on Cohen’s d for age (small: 0.20, medium: 0.50, large: 0.80) or η2 (eta-squared) for proportion of condom use and number of sexual partners (small: 0.01, medium: 0.06, large: >0.14); Cramer’s V (weak: 0.10-0.30, medium: 0.40-0.50, large: >0.50) was used for all categorical variables (intervention condition, gender, living status).
