  1. aDifferences in BMI, dietary intake, diet quality and physical activity 5.5 years after randomization between the intervention and the control group were analysed by linear regression models, with the exception of meeting the Dutch physical activity guidelines which is analysed by logistic regression. SD = standard deviation; kcal = kilocalories; en% = percentage of total energy intake; DHD 15-index score = Dutch Healthy Diet index 2015; PA = physical activity; MVPA = moderate to vigorous physical activity; min/day = minutes per day
  2. bBMI is self-reported
  3. cAdjusted for: Caucasian origin (yes/no), education level (categorical: no education or primary school; secondary education; intermediate vocational education; higher vocational education and university), smoking (yes/no) and duration of infertility (months)
