  1. HIV, human immunodeficiency virus; Hb, hemoglobulin.
  2. Beta coefficient expresses the mean difference in distensibility. Positive sign corresponds to protective effect while minus sign to decreased distensibility.
  3. *All the significant variables of Table 2 (with p<0.05) were included. When the same characteristic was reported as both continuous and categorical, the continuous variable was preferred, (e.g. cholesterol in mg/dl vs. hypercholesterolemia).
