Figure 7. Forest plot of ART adherence among HIV-infected FSWs.

Study estimates are grouped by country income and ordered by time on ART. The star symbol (*) highlights the study estimates (one per study population) included in the pooled overall or subgroup estimates. Only study estimates with a known sample size of at least 10 FSWs were used for pooling. For studies providing estimates over multiple time-periods, only one estimate was used for pooling (the most recent estimate from that study). I² and p-values are the measures of heterogeneity used. ART  =  antiretroviral, FSW  =  female sex workers, CI  =  confidence interval, NR  =  not reported, n =  number of FSWs with each outcome, N =  sample size of FSWs available for each outcome, N_p =  number of independent study populations, m =  median, PDI  =  peer driven intervention, PC  =  pill count, SR  =  self-report, VAS  =  visual analog scale.
