From: The accuracy of parent-reported height and weight for 6–12 year old U.S. children
Concordance between height, weight, and BMI, calculated using parent-reported and investigator-measured height and weight. a Child height, ρc = 0.007 (95% CI: -0.066, 0.079). b Child weight: ρc = − 0.039 (95% CI: −0.113, 0.036). c BMI (kg/m2), ρc = − 0.005 (95% CI: −0.080, 0.071). NOTE: ρc is the concordance correlation coefficient, where a value close to 1.0 (and a 45° fitted line) would suggest perfect concordance
