This revealed that while male AIDS patients with cryptococcal meningitis had significantly higher CD4+ T lymphocyte counts upon admission to the hospital (p = 0.016, Figure 1), they had an increased risk of death in the hospital (OR  = 1.8 (0.7−4.9)), even after adjusting for CD4+ lymphocyte counts (OR adjusted  = 5.2 (0.9−29), Gregory Bisson, personal communication). This evidence concerns the gene CD4 and Cryptococcal meningitis.
