About this table

KNGC2017 uses WHO standards from birth to 35 months and Korean data from 3 years. What can be read from it is height and weight for 3–7 years. Its head-circumference series breaks between 72 and 73 months and its BMI series does not agree with its own height and weight, so neither is usable.
At 3 years, height and weight switch from WHO to Korean data, and the z-score steps up slightly because the Korean median is a little higher. That is the seam between two tables, not a change in growth.
