  • Data are means ± SD or median (interquartile range) unless otherwise indicated. 2-h SDM, 2-h value of the OGTT decisive for diagnosis, with none or only one elevated fasting value; FPG, fasting plasma glucose; 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.

    * Non-OGTT-SDM significantly different from OGTT-SDM;
