Effect of treatment duration and age on AM and TLM subset frequencies. To assess the effect of treatment and age on AM and TLM subset distribution we arbitrarily divided 69 of the 70 treated patients presented in Table 1 into 5 groups: 13 young with short treatment periods (YS) [age 21-30 and mean (range) length of ART treatment 1.8 (1-6) months], 5 young with long treatment periods (YL) [age 21-30 and 28.4 (18-48) months of ART], 23 in the middle age group with long treatment periods (ML) [age 31-50 and 66.8 (16-160) months of ART], 8 aged with short treatment periods (AS) [age 51-64 and 5.6 (2-12) months of ART], and 20 aged with long treatment periods (AL) [age 51-64 and 87 (15-163) months of ART]. We had only one patient in the middle group with a short treatment period and accordingly we excluded this patient from the analysis. The treated patients were compared to the control group divided into young (YC; N = 27), middle (MC; n = 38) and aged (AC; n = 36) according to Table 1. * = P < 0.05, ** = P < 0.01, *** = P < 0.001.
