*HIV serostatus based on self-reported result of most recent HIV test.
†Among HIV-negative men, breakdown of STI diagnoses was 54% bacterial, 34% viral, 12% both; among HIV-positive men, breakdown of STI diagnoses was 71% bacterial, 18% viral and 11% both.
‡Behavioural category p-value compares the frequency of behaviour categories (ie, conventional risk reduction behaviours vs seroadaptive behaviours vs no strategy) rather than specific strategies.
STI, sexually transmitted infection; UAI, unprotected anal intercourse.
