GDM: gestational diabetes; OGTT: oral glucose tolerance test; GCT: glucose challenge test; EM: Ethnic Minority Backgrounds; T2DM: type 2 diabetes; Multivariable logistic regression with odds ratio (OR) adjusted for age, BMI, ethnicity and breastfeeding. Data are presented as OR (95% CI lower-upper limit). P values in bold are statistical significant.
