Figure 4: Impact of the relative protection ( 0 – no protection, 1 – equal protection) for sharers compared to perfect adherers and for users exposed to drug-resistant compared to wild-type HIV on A) relative CPF and B) relative TDR. Relative metrics (CPF and TDR) are calculated as the ratios of their values for scenarios with pill sharing over baseline scenario (no sharing). All other epidemic and intervention parameters are fixed on their baseline values from Table 1.
