Study estimates are grouped by country income and ordered by time-period. The star symbol (*) highlights the study estimates (one per study population) included in the pooled overall or subgroup estimates. I² and p-values are the measures of heterogeneity used. ^a Sample is ‘active’ FSWs, ^b Sample is ‘active’ and ‘former’ FSWs. ART  =  antiretroviral therapy, FSW  =  female sex workers, CI  =  confidence interval, n =  number of FSWs with each outcome, N =  sample size of FSWs available for each outcome, N_p =  number of independent study populations.
