Data were evaluated using Spearman correlation analyses.
SBP: systolic blood pressure, DBP: diastolic blood pressure, FCP: fasting C-peptide, 30 min CP: 30-minute postprandial C-peptide, 120 min CP: 120-minute postprandial C-peptide, HbA1c: haemoglobin A1c, TC: total cholesterol, HDL-C: high-density lipoprotein cholesterol, and LDL-C: low-density lipoprotein cholesterol.
