approached significanceP = 0.063
The interaction between genotype and mouse model approached significance ( P = 0.063), and contrast analysis within each mouse model indicated trisomic Ts65Dn mice had a significantly lower trabecular composite score than their euploid littermates ( P < 0.001) while trisomic Ts66Yah mice were not significantly different from their euploid littermates ( P = 0.207).
