GPT and diabetes mellitus: The analysis demonstrated significant positive associations of C-IMT with age (r = 0.531; p < 0.001), BMI (r = 0.226; p < 0.001), WC (r = 0.246; p < 0.001), diabetes duration (r = 0.240; p < 0.001), SBP (r = 0.280; p = 0.005), DBP (r = 0.164; p < 0.001), TC (r = 0.121; p = 0.002), LDL-c (r = 0.110; p = 0.004), GGT (r = 0.179; p < 0.001), and hsCRP (r = 0.361; p < 0.001) in the 722 subjects with T1DM, but no significant correlations were found between C-IMT and TG, fasting glucose, ALT, and AST (see Supplementary Table S1).
