(A) Correction factor for elastic modulus as a function of bone volume fraction. The linear regressions for each site had statistically equivalent slopes and intercepts (p > 0.24, ANCOVA), indicating that anatomic site did not contribute to the side-artifact error after accounting for differences in BV/TV. The pooled data set was also well-described by a power law relationship. (B) Trabecular spacing was the only significant predictor of the correction factor for elastic modulus from stepwise multiple regression (p < 0.0001). (C) Correction factor for yield stress as a function of BV/TV. ANCOVA indicated that anatomic site did not significantly contribute to the correction factor for yield stress after accounting for differences in BV/TV (p = 0.84). (D) Stepwise multiple regression analysis showed that structure model index was the only significant predictor of the correction factor for yield stress (p = 0.001).
