Scatter plots demonstrating the relationships between measures of trabecular bone architecture in the distal femur (i.e., appBV/TV, appTb.N, appTb.Th, and appTb.Sp) and 1) midthigh muscle volume/femur length2.77 while statistically controlling for femur length, sex, MVPA (min/d) and calcium intake (A-D) and 2) femur length while statistically controlling for midthigh muscle volume/femur length2.77, sex, MVPA (min/d) and calcium intake (E-H) in pre- and early-pubertal boys ● and girls ○. Because no sex effect was detected, the solid line represents the regression line for the combined sample.
