Changes of glucose and hormones levels during MMTT in individual groups. Mean and 95% confidence intervals are shown for glucose, GIP and glucagon. Insulin, C-peptide and GLP-1 follow approximately log-normal distribution so geometric mean (equivalent to arithmetic mean in log transformed data) and 95% confidence intervals are displayed. Confidence intervals were obtained in all cases by 10,000 times bootstrapping. Blue–for women with impaired fasting plasma glucose, red—for healthy pregnant women, green – for non-pregnant healthy controls
