*For inclusion in this analysis, patients must have had a CD4 cell count measured within 1 month prior to or up to 3 months after the date of HIV diagnosis while remaining antiretroviral-naïve. †By Jonckheere-Terpstra nonparametric test for continuous variables. ‡Differences in CD4 counts by race/ethnicity, HIV infection risk group, insurance, and type of facility were all statistically significant (nonparametric Wilcoxon rank sum test ).
