  • Data are means ± SD for continuous variables and median (interquartile range) for triglycerides. High total cholesterol: cholesterol >5.0 mmol/l; low HDL cholesterol: HDL cholesterol <1.0 mmol/l for men and HDL cholesterol <1.1 for women; high LDL cholesterol: LDL cholesterol ≥3.0 mmol/l; high triglycerides: triglycerides >2.0 mmol/l; high cholesterol/HDL cholesterol ratio >5. Obesity: BMI ≥30 kg/m2. Hypertension: diastolic blood pressure ≥90 mmHg, systolic blood pressure ≥140 mmHg, and/or use of antihypertensive medication. 2-h SDM group, 2-h value of the OGTT decisive for diagnosis, with none or only one elevated fasting value; mixed SDM group, two elevated fasting values or two elevated fasting and elevated 2-h values; non-OGTT SDM, patients with fasting capillary glucose >8.5 mmol/l, diagnosed on two fasting values, with no OGTT performed; OGTT-SDM, patients diagnosed on OGTT.

    * High fasting SDM significantly different from OGTT-SDM;

  • 2-h SDM significantly different from mixed SDM.
