Table 5. Summary estimates of the fraction of infections prevented in the wider population, when interventions were focused on FSWs, in the absence of risk compensation.

Median prevented fraction (range, Ns), HIV prevalence ≤5%
Time-horizon for outcome assessment ≤5 years Time-horizon for outcome assessment >5 years
Intervention efficacy≥60%* 20.5% (7 to 43, Ns = 12α) [24], [30] 59.0% (40 to 100, Ns = 47αγ) [27], [30], [31]

Population in which the outcome was measured includes: αlow-risk females; βgeneral population (excludes high-risk groups); γtotal population (includes high-risk groups); ωante-natal clinic attendees.STI (sexually transmitted infection). Ns refers to the number of simulated scenarios. Summary estimates reflect the median and range if ≥5 scenarios across at least 2 studies were available within each category. Estimates were grouped across intervention-related characteristics. *Efficacy in reducing HIV susceptibility per sex act (or transmission probability if intervention effect on HIV susceptibility was not differentiated from intervention effect on HIV infectivity). FSW (female sex worker).
