Extended Data Fig. 14. Linear growth velocity by age and sex stratified by region.
a) Within-child difference in length in centimeters per month stratified by age, sex, and region. Dashed black line indicates 25th percentile of the WHO Growth Velocity Standards; solid black line indicates the 50th percentile. Colored lines indicate and vertical bars indicate 95% confidence intervals for ki cohorts. Light gray lines indicate cohort-specific linear growth velocity curves. (b) Within-child difference in length-for-age Z-score per month by age, sex, and region. Smaller partially transparent points indicate cohort-specific estimates. Results shown in all panels were derived from 32 ki cohorts in 14 countries that measured children at least quarterly (n = 52,640 children).
