Latent growth curve modelling was used to derive distinct body height trajectories from 0 to 11 years (A) and from 0 to 18 years (B) of individuals in The Danish National Birth Cohort. The figures display the class-specific estimated average height (z-scores) for age with 95% confidence intervals. The normal height groups in both figures were characterized as having a birth length above the mean, which was expected since z-scores were made according to the WHO-reference and Scandinavian newborns are generally longer at birth
