aA total of six participants (control: n=2; PlayForward: n=4), who at baseline were identified (per primary outcome definition) as being engaged in sexual intercourse, were removed from the primary analysis because they had already reached the primary outcome.
bExact 95% confidence intervals are provided for the main outcome (delay of initiation of sexual intercourse).
cP values are based on a two-sided Fisher exact chi-square test.
