The 50th, 90th and 95th percentile of SBP and DBP for the median height for Chinese (CHNS) and American boys (A) and girls (B). SBP and DBP values for American children with the given age (years) and height (cm) were computed based on SBP and DBP equations from the table B1 of the Fourth Report , without exclusion of overweight or obese children. It shows that American boys and girls at given age and height (cm) according to Chinese children had higher SBP and DBP percentile levels (the 50th, 90th and 95th ). A, SBP for boys; B, DBP for boys; C, SBP for girls; D, DBP for girls. Pn _ncn indicates the existing national centile curves, Pn_us indicates corresponding expected centile curves of American children based on equations in Table B1 in .
