Table 5. Regression* Coefficients of CTI, HT and WT in the nBMD Prediction Model.
| Predictor | Female | Male | ||
|---|---|---|---|---|
| B (95% CI) | β | B (95% CI) | β | |
| Constant | −0.523 (−0.71 to −0.337) | - | −0.581 (−0.941 to −0.22) | - |
| CTI† | 0.651 (0.531 to 0.772) | 0.441 | 0.825 (0.629 to 1.022) | 0.446 |
| HT† | 0.004 (0.003 to 0.005) | 0.252 | 0.004 (0.001 to 0.006) | 0.200 |
| WT† | 0.003 (0.002 to 0.004) | 0.249 | 0.004 (0.002 to 0.006) | 0.295 |
CTI: cortical thickness index, HT: height, WT: weight, nBMD: femoral neck bone mineral density, B: unstandardized coefficient, CI: confidence interval, β: standardized coefficient.
*Multiple linear regression analysis. †All three variables (CTI, HT, or WT) significantly added to the prediction (p < 0.001). The canal flare index was eliminated from the regression model (p > 0.05).
