*OR, odds ratio; CI, confidence interval.
†p value obtained by using matched-pairs signed-ranks test.
‡CD4 count not measured in 4 HIV-1–infected case-patients, 1 control with uncomplicated malaria, and 1 asymptomatic control because of technical constraints. p value obtained by using Wilcoxon signed-ranks test and Wilcoxon rank-sum test.
