Data are mean ± SD or median (interquartile range). BMI: body mass index; hypertension: systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg or treatment; MDA-LDL: malondialdehyde-modified LDL; MDA-LDL-C/LDL-C: MDA-LDL-to-LDL cholesterol ratio; MDA-LDL-C/HDL-C: MDA-LDL-to-HDL cholesterol ratio; (MDA-LDL/LDL-C)/HDL-C: (MDA-LDL/LDL-C) to HDL cholesterol ratio.
