  1. Abbreviations: GDM Gestational Diabetes Mellitus by IADPSG criteria, LGA Large for Gestational Age Delivery defined as ≥ 90th customized birthweight centile [26]. Customized centiles are adjusted for maternal age, height, weight, ethnic group, gestational age and gender. Weight adjustment for women with BMI ≥ 30 Kg/m2 (all women in study) is based on a notional weight corresponding to a BMI of 29.9 Kg/m2.
  2. Continuous variables are given as mean (SD) with Mean Difference & 950025 CI. Binary outcomes are n (%), with Risk Difference and risk ratio.
