Figure 2. Planned pairwise comparisons indicated that a) among individuals currently prescribed ART, regular stimulant users (n = 64) had a five-fold higher HIV viral load (0.70 log₁₀) than those who denied regular stimulant use (n = 465; 2238 versus 447 copies/mL); b) regular stimulant users on ART (n = 64) had significantly lower HIV viral load (0.62 log₁₀) when compared with regular stimulant users who were not prescribed ART (n = 50); and c) among individuals who denied regular stimulant use, individuals currently prescribed ART (n = 465) had significantly lower HIV viral load (1.27 log₁₀) when compared with those not currently treated with ART (n = 183).
