  • Data are medians (interquartile range) or %. Impaired glucose tolerance (IGT): fasting plasma glucose (FPG) level <7.0 mmol/l and 2-h glucose ≥7.7 and <11.1 mmol/l. Impaired fasting glucose (IFG) only: FPG level ≥6.1 mmol/l and <7.0 mmol/l and 2-h glucose <7.7 mmol/l. Normal glucose tolerance (NGT) and normal fasting glucose (NFG) only: FPG level <6.1 mmol/l and 2-h glucose <7.7 mmol/l. AUC denotes area under the curve during the oral glucose tolerance test.
