GSTM1 and type 2 diabetes mellitus: The multivariable analysis demonstrated that LVH was significantly correlated with BMI (OR = 0.93, P = 0.001), waist (OR = 0.97, P < 0.001), Hb (OR = 1.008, P = 0.012), Cr (OR = 1.015, P < 0.001), HDL-c (OR = 0.5, P < 0.001), gender (OR = 0.215, P < 0.001), and sleep duration (OR = 1.093, P = 0.022) for T2DM patients (Table 2).
