Data presented as mean (SD) and range. For continuous variables, P was calculated by two-tailed t test, and for categorical variables, P was calculated by chi-square test or Fisher’s exact test. Two women from the GDM group only had fasting blood samples taken at the follow-up visit. Eleven samples of fasting glucose were coagulated and rejected by the department investigating glucose
