For each group, n=13. Within rows, means with the same superscript letter are significantly different at p<0.05. ANOVA with F ratio provided for age, years of education, reading grade level, years with HIV, and age at infection; Chi squares with Pearson χ2 provided for sex, ethnicity, and race; Wilcoxon/Kruskall-Wallis tests for current CD4, nadir CD4, and plasma HIV RNA load

^*Hispanic individuals endorsed African American (n=8), Caucasian (n=4), and multiple or other (n=4) race

^**Reading grade level was determined by the WRAT-4 reading test.

^***With Bonferroni correction for multiple comparisons, not significant
