Figure 1.

This figure shows the breakdown of PrEP use status at each assessment time point among the analytic sample, which is comprised of the 137 participants who were PrEP-naïve at baseline and initiated PrEP at some point prior to the 24-month assessment. As can be seen, there were a small number of PrEP discontinuations and assessments not completed, resulting in a total of 393 time points for analyses. The figure also illustrates that some individuals had two pre-PrEP assessments and one assessment on PrEP, while others had one pre-PrEP assessment and two assessments on PrEP, for a total of 206 pre-PrEP time points and 184 time points while on PrEP available for within-person analyses.
