Subgroup analysis of the total population was performed according to age (< 65 or ≥ 65 years), sex (female or male), BMI (< 24 or ≥ 24 kg/m2), current smoking (yes or no), hypertension (with or without), dyslipidemia (with or without), T2DM (with or without), LDL-C (< 1.8 or ≥ 1.8 mmol/L), and HbA1c (< 6.5% or ≥ 6.5%) to further verify the utility of AIP for identifying poor CCC in different subgroups. This evidence concerns the gene AIP and type 2 diabetes mellitus.
