For patients with low dose EFV (400mg), whose median BMI (P = 0.016), rates of high VL (VL ≥ 100,000 copies/mL, P=0.014) and opportunistic infections (P < 0.001) were lower than with DTG, while median CD4+ T-cell count (P = 0.002) and CD4/CD8 ratio (P < 0.001) were higher (Supplementary Table 1). Here, CD4 is linked to Opportunistic infection.
