  1. BCCG Box-Cox Cole and Green distribution, SD Standard deviation, GAMLSS Generalized Additive Models for Location, Scale and Shape, SE Standard error
  2. * = p < 0.05, ** = p < 0.01, *** = p < 0.001
  3. Differences in mean, variability and skewness estimated by GAMLSS
  4. aadjusted for parental education, BMI, and country. NO: normal distribution
  5. bSkewness is estimated as the Box-Cox power (that is, the power required to transform the outcome to a normal distribution, values closer to 1 represent less skew)
