CD4 and tuberculosis: Due to patient matching, the median age (33.2 years, interquartile range [IQR] 27.7–40.8 vs. 33.4, IQR 28.2–42.4, P = 0.992), sex distribution (64.7% male vs. 64.7% female, P = 1.0) and median CD4 cell counts (102 cells/μ l, IQR 35–212 vs. 102 cells/μ l, IQR 42–186, P = 0.718) were similar between the two TB patient groups.
