Second, both NVP-associated and EFV-associated rashes occurred more often among patients starting ART with a low CD4 count, with the adjusted HRs (95% CI) of developing a NVP-associated or an EFV-associated rash with CD4 counts below 100 cell/mm3 of 1.48 (1.09–2.03) and 1.61 (1.09–2.39) respectively. Here, CD4 is linked to Skin rash.
