GSTM1 and diabetes mellitus: Interestingly, the correlation to DM has been preserved for the miR-150 group (Spearman coefficient r = 0.568; p-value = 0.014), miR-101 (r = 0.477; p = 0.045), miR-21 (r = 0.2715; p = 0.038) in the Hb 13–15 g/dL group, and only for miR-150 (r = 0.363; p = 0.049) in the Hb > 15 g/dL group.
