a
Baseline is within −30 to +183 days of the documented HIV-positive date.
b
Values are represented as mean (standard deviation) for continuous values and number (percentages) for categorical variables unless otherwise stated.
c
Cohort sizes were as follows: total, n = 1,097; underweight, n = 13; normal, n = 543; overweight, n = 448; obese, n = 93.
d
P value calculated from analysis of variance for continuous variables or chi-square test for categorical variables.
e
IQR, interquartile range.
