INS and gestational diabetes: When analysing the predictors without “a previous history of GDM”, results were similar, i.e., fasting glucose, gravida and diastolic blood pressure in pregnancy were the best predictors for all women (all p ≤ 0.007), and fasting glucose for the “insulin-deficient” cluster and NW women (all p ≤ 0.004, Supplementary Table 4.A).
