Data are presented as mean ± standard error. P-value by paired t test. NS, not significant; TSEC, tissue-selective estrogen complex; OD, outer diameter; CSA, cross-sectional area; CSMI, cross-sectional moment of inertia; SM, section modulus; CT, cortical thickness; BR, buckling ratio.
In bold: statistically significant p-values.
