*HIV-1 viral load and CD4+ cell counts were measured as described in Patients and Methods. Significance of differences between groups was tested by Kruskal-Wallis test or Fisher exact test. Analysis was carried out on the whole study group (N = 103) or restricted to those who did not receive treatment (n = 61). IQR, interquartile range; ARV, antiretroviral.
†Kruskal-Wallis test.
‡Fisher exact test.
§Statistically significant (p<0.05) by directional test.
