Table summary
 This table displays the results of equations to predict national institutes of health waist circumference measures (wc_nih_predicted) based on waist circumference measured using world health organization protocols (wc_who). The information is grouped by age group (years)/sex (appearing as row headers), equation and r (appearing as column headers).
Age group (years)/Sex Equation R2
3 to 19  
Boys WC_NIH_predicted = -0.89911 + 1.01829*(WC_WHO) + 0.05164*(age) 0.99
Girls WC_NIH_predicted = -0.70299 + 1.01891*(WC_WHO) + 0.12297*(age) 0.99
20 to 79  
Men WC_NIH_predicted = 3.83072 + 0.98613*(WC_WHO) - 0.03609*(age) 0.99
Women WC_NIH_predicted = 3.53771 + 0.98479*(WC_WHO) + 0.21949*(x) (where x is set to 1 if age is 20 to 39; otherwise x=0) 0.98
