CD4 and AIDS: Regarding the variables being examined, patients whose cause of death was AIDS-related were more likely than other patients to have lower DHEA-S levels, CD4+ T cell counts, hemoglobin levels, albumin levels, and serum sodium levels (t = 3.349, P = 0.001; z = −2.805, P = 0.005; t = 2.418, P = 0.017; t = 2.279, P = 0.024; t = 4.029, P = 0.000), while they were also more likely to have higher cortisol and ACTH levels (t = −3.008, P = 0.003; t = −1.897, P = 0.060).
