^∗ p < 0.05; ^#p < 0.001. AHI was log-transformed. For BFP and VAT area, model 1 without adjustment and model 2 was further adjusted for gender, T2DM duration, regular drinking, current smoking, and hypertension. Model 3 was further adjusted for BMI, HbA1c, TG, LDL-c, and HDL-c. For CVAI, model 1 without adjustment and model 2 was further adjusted for gender, T2DM duration, regular drinking, current smoking, and hypertension. Model 3 was further adjusted for HbA1c and LDL-c.
