Midslice scaling exponents.

Phylogenetically corrected scaling exponents, a±95% CI, were calculated for midshaft parameters (y) versus bone length (l). The exponent expected for the isometric case is in parentheses. Statistically significant (p<0.05) relationships are indicated in bold. Scaling exponents tend to be greater than isometry, except for cortical thickness, which appears to scale at less than isometry. Full tables including correlation coefficients (r) and standard error (SE) are provided as supplementary information (Table S1).
dmax, maximum external diameter.
tav, mean cortical thickness.
CSA, cross-sectional area.
Zmax, maximum section modulus.
Imax, maximum second moment of area.
Jz, polar moment of inertia.
n.c., not calculated.
