  1. Pre- and post-intervention data are given as mean (SD), change as mean (95% CI)
  2. Abbreviations: CI confidence interval, SD standard deviation
  3. aPaired samples t test for comparison of individual pre- and post-intervention values within each intervention group
  4. bLinear mixed effect model adjusted for pre-intervention score and age
  5. cLinear mixed effect model adjusted for pre-intervention score, age, and compliance (amount of fish/meat consumed)
  6. dLinear mixed effect model adjusted for pre-intervention score, age, and interaction between treatment (intervention group) and compliance, mean values
  7. eLikelihood ratio test to compare the goodness of fit to the previous model
  8. A random intercept for kindergarten was included in all linear mixed model analyses
