In bivariate analysis, time to viral suppression was significantly associated with IDU history (p < 0.001), calendar year of cART initiation (p < 0.001), initial composition of ARV regimen (p < 0.001), baseline viral load (p < 0.001), baseline CD4 count (p = 0.001), HCV co-infection (p = 0.001), age (p = 0.002), ethnicity (p = 0.002), having an ADI at baseline (p = 0.006), and province of residence (p = 0.011). Here, CD4 is linked to coinfection.
