In fasting conditions investigators will consider normal blood glucose values <99 mg%, pre-diabetes between 100 and 125 mg% and diabetes ≥126 mg%. In non-fasting conditions values of blood glucose >200mg% will be considered as diabetes. Investigators will deem normal glycosylated A1c hemoglobin values <5.6 %, pre-diabetes between 5.7 and 6.4% and diabetes ≥6.5%.
