*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 Cochran-Armitage test for proportions (%), and by Jonckheere-Terpstra nonparametric test for continuous variables.
