AP: anterior-posterior, ML: medial-lateral, Ct.Ar: cortical area, IMAX, IMIN maximum and minimum principal moments of inertia, CAP, CML AP and ML radius of curvature, TMD: tissue mineral density, HA: hydroxyapatite. Different superscript letters indicate significant differences between age groups at p < 0.05. ANOVA (A) with Tukey-Kramer post hoc test and non-parametric Kruskall Wallis (KW) and post hoc Mann-Whitney U tests were used to distinguish age-related differences in the measured parameters.
