The relation of the SF sum to levels of PBFDXA for each child (points), along with the predicted relationship of the SF sum to PBF Slaughter(dashed line) and PBF DXA(solid line, lowess). For boys with a SF sum < 35 mm, the intercept of the SF sum vs. PBF Slaughter line varies by race and sexual maturation in the Slaughter equations,[26] and the illustrated line is for white, pubescent boys. Among pubertal (ages 12 to 13.9 y) boys who have a SF sum ≤ 35 mm, the estimated percent body fat is: -3.4 + 1.21*(SF sum) -0.008*(SF sum)2. For boys with a SF sum >35 mm, the equation is: 1.6 + 0.783*(SF sum) irrespective of pubertal stage
