  1. aData are given as mean ± SD; btest the change difference between two periods; cthe homeostasis model assessment index; dareas under the response curve to glucose and insulin were calculated from the fasting, 15, 30, 45, 60, 90 and 120 min serum glucose and insulin concentrations using the trapezoid rule
