GSTM1 and tuberculosis: Within the obese group (n = 350), TB levels correlated positively and significantly with age (r = 0.284, p<0.001), height (r = 0.285, p<0.001), weight (r = 0.219, p<0.001), BMI (r = 0.123, p = 0.021), Hb (r = 0.305, p<0.001), Ht (r = 0.352, p<0.001), MCV (r = 0.394, p<0.001), MCH (r = 0.301, p<0.001) and correlated negatively and significantly with BMI z-score (r = –0.131, p = 0.014), MCHC (r = –0.149, p = 0.006) and CRP (r = –0.178, p = 0.001).
