Continuous variables are shown as for parametric data or median (interquartile ranges) for nonparametric data. Categorical variables are expressed as numbers and percentages. Abbreviations: BP: blood pressure; CVD: cardiovascular disease; HbA1c: hemoglobin A1c; HDL-c: high-density lipoprotein cholesterol; LDL-c: low-density lipoprotein cholesterol; ALT: alanine aminotransferase; AST: aspartate aminotransferase; eGFR: estimated glomerular filtration rate; baPWV: brachial-ankle pulse wave velocity; DR: diabetic retinopathy. indicates the difference among the three groups reaching significance.
