Multiple R2 values for various regression models predicting PBFDXA

Predictors* Boys Girls
Race, age (baseline) 0.11 0.04
 + BMI 0.75 0.76
 + triceps skinfold thickness 0.85 0.77
 + subscapular skinfold thickness 0.78 0.73
 + SF sum 0.86 0.81
Race, age, and BMI (baseline) 0.75 0.76
 + triceps skinfold thickness 0.86 0.83
 + subscapular skinfold thickness 0.81 0.80
 + SF sum 0.87 0.84

All models include race and age (top rows) or race, age, and BMI (bottom rows). Age, BMI, and the skinfold thicknesses were modeled with the use of restricted cubic splines.
