Extended Data Fig. 1: Efficacy of TDF/FTC by TFV-DP measurement in model h2.

Reduction in incidence in HIV as a function of tenofovir diphosphate (TFV-DP) levels in dried blood spots measurement according to model h_2. Grey ribbon = IQR, Dashed line = 95% Credible Interval. Colored rectangles represent the IQR of TFV-DP measurements associated with two pills per week (red), four pills per week (blue) and seven pills per week (green) derived from directly observed dosing8.
