Table shows result for regression between height, LM, FM, and PC, with or without adjustment for height, in 1851 boys and 2154 girls. Pooled coefficients PC, height β = 0.509; 95% CI, 0.482, 0.536; P = 0.0001. Pooled coefficients EC, PC adj height/FM/LM β = 1.117; 95% CI, 1.088, 1.146; P = 0.0001; LM adj height/PC β = −0.597, 95% CI, −0.642, −0.553; P = 0.0001; FM β = 0.182, 95% CI, 0.147, 0.218; P = 0.0001.
