ART = antiretroviral therapy; BMI = body mass index in kg/m2; CD4 = CD4+ T lymphocyte count in cells/mm3; HSCL = Hopkins Symptom Checklist; IARSS = Internalized AIDS-Related Stigma Scale; IQR = interquartile range; SD = standard deviation; UARTO = Uganda AIDS Rural Treatment Outcomes.
Results listed as n (%) unless otherwise noted. Tests of association were performed using Chi-squared, Wilcoxon rank sum, and t-tests.
The asset index variable was calculated using principal components analysis. By definition, the within-cohort mean is equal to zero. Positive scores indicate increasing wealth, and negative scores indicate decreasing wealth.
