Table 3. GST genotypes distribution in study population.

Genotypes ART
(N = 105)
ART-naïve
(N = 77)
Control
(N = 60)
Total
GSTM1 null 25 (47.1) 17 (32.1) 11 (20.8) 53
GSTT1 null 20 (41.7) 16 (33.3) 12 (25.0) 48
GSTM1 + GSTT1 51 (42.5) 42 (35.0) 27 (22.5) 120
Both null 9 (42.9) 2 (9.2) 10 (47.6) 21

N is the population of the subgroups. Genotype frequency is expressed as n (%), where n is the total number of patients with defined genotype.
