Comparison of Success of IBW Measurement by each IBW Method and Effect of Age on Successful Measurement

Comparison Metric	IBW Measurement Method
Comparison Metric	NCHS	McLaren	Moore	BMI
IBW measurement possible, n(%)	576 (98)	530 (90)	576 (98)	357 (61)
Age if measurement is possible, years^a	4 (0.7–11)	4 (0.8–11)	4 (0.7–11)	10 (5–14)
Age if measurement is not possible, years^a	0.2 (0.1–0.17)	0.5 (0.1–15)	0.2 (0.2–0.9)	0.3 (0.1–0.9)
p-value for age difference between IBW possible & not possible	<0.0001	0.4	0.02	<0.0001

Expressed as median (interquartile range).
