Data distribution between 1.5T and 3T subgroups
| Dehiscence CT and MRI (No.) | Dehiscence CT Only (No.) | Dehiscence MRI Only (No.) | No Dehiscence on Both CT and MRI (No.) | |
|---|---|---|---|---|
| SSC | ||||
| 1.5T | 5 | 0 | 2 | 72 |
| 3T | 6 | 0 | 5 | 123 |
| P value for distribution comparison (Fisher exact test) = .80a | ||||
| PSC | ||||
| 1.5T | 1 | 0 | 0 | 79 |
| 3T | 0 | 0 | 2 | 133 |
| P value for distribution comparison (Fisher exact test) = .29a | ||||
↵a A P value ≥ .05 means that the hypothesis of equality between the 2 distributions is not rejected by the Fisher exact test.
