Abstract
Using intraerythrocytic tenofovir-diphosphate data from the emtricitabine/tenofovir disoproxil fumarate arms of HIV Prevention Trials Network (HPTN) 083 (men) and HPTN 084 (women), approximately 99% efficacy was achieved at a lower adherence threshold in HPTN 083 (≥2 doses/week) compared with HPTN 084 (daily), suggesting higher adherence is necessary for women vs men.
