Stepwise linear regression model for the development of symptomatic spinal cord retethering and syringomyelia after trauma in need for surgical revision (n = 25).
| Stepwise Linear Regression Model | B-Coefficient (SE) | P |
| Location of SCI | 0.406 (0.273) | 0.044 |
| Age | 0.087 (NA) | 0.718 |
| Duraplasty (Gore-Tex) | −0.315 | 0.105 |
| Duraplasty (polyesterurethane) | 0.295 | 0.147 |
| Duraplasty (bovine pericardium) | 0.316 | 0.104 |
Abbreviations: NA, not applicable; SCI, spinal cord injury.
Note: Stepwise method was performed including the predictor variables age, type of duraplasty, and location of SCI.
