  • *HIV serostatus based on self-reported result of most recent HIV test.

  • †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.

  • UAI, unprotected anal intercourse.
