The analyses revealed that isolated IGT (β = 0.044, p 0.002), combined IFG/IGT (β = 0.032, p 0.023) and type 2 diabetes (β = 0.076, p < 0.001) were significantly associated with the QTc interval after adjusting for all potential confounders (age, sex, insulin, SBP, DBP, CHOL, TG, smoking, and drinking) (Table 4). The gene discussed is INS; the disease is type 2 diabetes mellitus.
