Values are N (%), mean ± SD. BMI: body mass index (calculated as weight in kilograms divided by height in meters squared); SBP: systolic blood pressure; DBP: diastolic blood pressure; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; eGFR: estimated glomerular filtration rate; TyG: triglyceride-glucose.
