Mean PWID treatment enrollment frequency (95% CI) for DAA treatment rate of 7.5% per year with 1–3 (Treatment Limit = 3) or 1–4 (Treatment Limit = 4) DAA courses permitted, and treatment adherence (TA) of 90% (A) and 70% (B).

Number treated values are rounded to the nearest integer. Percent treated is the fraction of PWID treated by number of times in each row relative to the total number of all individual PWID treated. The related DAA cost is shown in Table 4. Entries marked with (*) indicates scenario does not achieve WHO incidence elimination goal.
