Compared to females, males were older (median age 36 vs. 30 years, p < 0.001), had lower BMI (median 20.2 vs. 22.3 kg/m2, p < 0.001), lower CD4 counts (median 139 vs. 183 cells/μl, p < 0.001), and were more likely to report a history of prior opportunistic infection (46.2% vs. 39.1%, p = 0.01). Here, CD4 is linked to Opportunistic infection.
