Statistical consequences of using bone mineral density to pair cadaver femurs in comparative ex vivo hip fracture studies

[摘要] ObjectiveIn ex vivo hip fracture studies femoral pairs are split to create two comparable test groups. When more than two groups are required, or if paired femurs cannot be obtained, group allocation according to bone mineral density (BMD) is sometimes pe
