Table 3 Multivariate logistic regression analysis.
| Index | OR | 95% CI LB | 95% CI RB | P value |
|---|---|---|---|---|
| Intervertebral height/adjacent intervertebral height | 5.893E-6 | 5.159E-16 | 67326.045 | 0.308 |
| Preoperative ROM of the replacement segment (°) | 14.188 | 0.234 | 858.611 | 0.205 |
| Postoperative ROM of the replacement segments (°) | 0.576 | 0.005 | 68.986 | 0.821 |
| The upper prosthesis-endplate sagittal distance (mm) | 0.000 | 3.824E-7 | 0.327 | 0.023 |
| The lower prosthesis-endplate sagittal distance (mm) | 16.598 | 0.211 | 1306.906 | 0.207 |
| Number of replacement segments (n) | 0.105 | 0.001 | 7.777 | 0.305 |
| ROM – range of motion. # Indicates a significant interaction between the effect of HO and the upper prosthesis-endplate sagittal distance. | ||||
