CI, confidence interval; DIP, Atlantic Diabetes in Pregnancy Study; HAPO, Hyperglycemia and Adverse Pregnancy Outcome Study. aThese analyses were performed in HAPO as it was a representative sample of pregnant women of European ancestry. bAs ATLANTIC-DIP had a case-control design the beta coefficients will not be representative of the general pregnant population but are presented for comparison with HAPO. cThe 1-hour and 2-hour glucose measures refer to the glucose level measured at 1 and 2 hours, respectively, following a 75 g oral glucose load as part of an oral glucose tolerance test. ** P value <0.001, <0.01 after Bonferroni correction. *** P value <0.001, remained <0.001 after Bonferroni correction.
