The followed multivariable analysis demonstrated that LVH was significantly correlated with a sleep duration of 8 hours per day (OR = 1.563, P < 0.001), Hb (OR = 1.009, P = 0.001), BUN (OR = 1.093, P = 0.002), and HDL-c (OR = 0.612, P = 0.001) for T2DM patients (Table 3). The gene discussed is GSTM1; the disease is type 2 diabetes mellitus.
