Stepwise linear regression models for the development of symptomatic spinal cord tethering and syringomyelia after trauma in need for surgical intervention (n = 25).
| Stepwise Linear Regression Model | B Coefficient (SE) | P |
| Model 1 | ||
| Age | 0.478 (0.169) | 0.013 |
| Extent of spinal cord tethering/syringomyelia | 0.396 (0.468) | 0.034 |
| Location of SCI | 0.254 (NA) | 0.200 |
| Model 2 | ||
| Location of SCI | 0.621 (0.404) | 0.002 |
| WBC count | 0.357 (1.032) | 0.048 |
| Age | 0.319 (NA) | 0.080 |
| CRP | –0.103 (NA) | 0.585 |
Abbreviations: CRP, C-reactive protein; NA, not applicable; SCI, spinal cord injury; WBC, white blood cell.
Note: Stepwise method was performed including the predictor variables age, location of SCI, and extent of spinal cord tethering/syringomyelia in model 1 and age, sex, location of SCI, CRP, and WBC in model 2.
