Note:
The first model was assessed using PGLS. All other models were assessed using OLS. ACT, absolute cortical thickness; RCT, relative cortical thickness; measured as the ratio of average cortical thickness to average total cross-sectional diameter. Significant p-values are indicated by asterisks. Abbreviations used in models: NHACT, neonate humerus ACT; NFACT, neonate femur ACT; NBM, neonate body mass; AHACT, adult humerus ACT; AFACT, adult femur ACT; ABM, adult body mass; AHRCT, adult humerus RCT; AFRCT, adult femur RCT; NHRCT, neonate humerus RCT; NFRCT, neonate femur RCT; DM, developmental mode.
