AIDS, acquired immunodeficiency syndrome; ICU, Intensive Care Unit; HAART, highly active anti-retroviral therapy. Significant differences are shown as ^aP < 0.05; ^bP < 0.01. Adjusted HR includes adjustments for age, CD4 count, time since AIDS diagnosis, HAART, location before ICU, and cardiovascular and respiratory dysfunctions.
