  1. Gestational weight gain analyzed as continuous outcome variable using Student’s t-test for unadjusted comparison of intervention and control groups, and multiple regression analysis including age, smoking status, educational level and income at trial inclusion. Analysis of weight gain prior to glucose testing also included gestational length at time of measurement (analysis from pre-pregnancy) or interval between measurements (analysis from trial inclusion)
  2. aGestational weight gain to term missing for 47 participants: 31 who delivered at <37 gestational-weeks (16 intervention, 15 control) and 16 without measured weight at or within 2 weeks of delivery (9 intervention, 7 control)
  3. bAn additional 6 participants were without measured weight at trial inclusion (5 intervention, 1 control)
  4. cWeight gain prior to glucose testing missing for 1 participant (intervention) without weight measured at glucose testing
  5. dAn additional 8 participants were without weight measured at inclusion (6 intervention, 2 control)
