  1. aNGT, normal glucose tolerance; IGT, impaired glucose tolerance. According to the WHO criteria (ref. 40)
  2. bIGT, defined as glucose at 0 minutes above 6.1 mmol/l and/or glucose at 120 minutes above 7.8 mmol/l
  3. cGradients calculated as the differnece between the 120 min and 30 min levels.
  4. dNegative: negative gradients; Positive: positive gradients
