CD4 and AIDS: Consistent with prior reports from CHARTER, analyses identified that NCI (n = 384, 37.4%) was associated with AIDS (65.6% vs. 58.2% in the 663 participants without NCI, p = 0.021), ART use (76.4% vs. 67.4%, p = 0.002), and lower nadir CD4+ T cell count (150 vs. 190/μL, p = 0.028), and more than minimal comorbidities (70.4% vs. 53.1%, p < 0.001).
