Figure 2. The effect of six-month PrEP dispensing + interim HIVST on recent HIV testing, PrEP refilling, and PrEP adherence at six months.

Figure 2.

These risk differences (RDs) compare the combined six-month PrEP dispensing + interim HIV self-testing (HIVST, either oral-fluid or blood-based) arm with the SOC PrEP dispensing arm at six months.

The red lines indicate the marker of significance. The bolded RDs and 95% confidence interval (CI) lower bounds (LB) indicate the primary pre-specified outcomes: recent HIV testing (green bars), PrEP refilling (blue bars), and PrEP adherence (red bars) among all participants (N=495). We additionally pre-specified analysis of these outcomes among the following sub-groups: individuals taking PrEP who were members of HIV serodifferent couples (N=295), all women (N=330, including those enrolled in couples and those singly enrolled), and women singly enrolled (N=200).
