| aBMD (g/cm2) | 0.877 (0.794 to 0.959) | 0.993 (0.922 to 1.064) | p < 0.001 |
| vBMD (g/cm3) | 0.358 (0.328 to 0.388) | 0.402 (0.384 to 0.420) | p < 0.001 |

BMD = bone mineral density, aBMD = areal bone mineral density (g/cm2), vBMD = volumetric bone mineral density (g/cm3), BMC = bone mineral content, CI = confidence interval, FN =femoral neck, Calc = calcaneus
