  1. Time points and age intervals include birth, birth to < 3 years of age, 2-18 years, birth to < 5 years and > 18 years. The number of subjects and data points (i.e. length/height, weight and head circumference) represented in the corresponding growth curves are presented in this table by sex at non-mutually exclusive age intervals. Overlapping age intervals include birth, birth to < 3 years of age, 2–18 years, and birth to < 5 years
