Figure 2. Proportion of participants classified as newly diagnosed by self-report only vs. self-report plus antiretroviral drug testing.

Figure 2.

Study participants who test positive for HIV infection can be classified as newly diagnosed based on self-report only (e.g., if they do not report having a prior positive HIV test) or based on both self-report and antiretroviral (ARV) drug testing (e.g., if they do not report having a prior positive HIV test and also do not have ARV drugs detected in study samples). The figure compares the portion of HPTN 074 participants classified as newly diagnosed using these two approaches using the mid-p McNemar’s test; p<0.05 is considered significant. Results are shown for each study site and for the three sites combined (Total).
