^*Bone mineral density measured by dual-energy radiograph absorptiometry (areal BMD) and high-resolution peripheral quantitative CT (volumetric BMD).

^†Cortical bone thickness measured on radiographs and CT scans.

^‡Single (n = 32) consisting of one of the 22 paired and ten single specimens.

^§Left/right (n = 22) each side of the 22 paired specimens.

aBMD, areal bone mineral density; CBTavg, mean average cortical bone thickness; CBTg, gauge cortical bone thickness; SD, standard deviation; vBMD, volumetric BMD; XR, radiograph.
