bw: body weight; n: number of surveys.
The corresponding 95% confidence intervals are presented in the brackets. Estimates are rounded to one decimal place.
Section 5.1 describes the age range within each age class.
One the dietary surveys had less than 60 survey participants and therefore could not be included in calculation of the 95th percentile exposure.
