  1. 1 Values are models adjusted hazard ratios (95% CI), HR hazard ratio
  2. 2 Values are min-max in tertiles in girls
  3. 3 P for trend across tertiles were performed by including total soy intakes at baseline as continuous variables
  4. 4 Adjusted for parental education level, energy intake at baseline, dietary fibre intakes (residuals) at baseline and mother’s age at menarche
  5. 5 Additionally adjusted for percent body fat at baseline
  6. 6 Values are min-max in tertiles in boys
