Table 3:
Statistical tests and P values of each variable that was correlated with the final recovery degree of CNPa
| Parameter | Statistical Test | P Value |
|---|---|---|
| Patient age | Spearman correlation | .157 |
| Aneurysm neck size | Fisher exact test | .458 |
| Duration of CNP before intervention (time interval) | Spearman correlation | .835 |
| Aneurysm size | Spearman correlation | .547 |
| Rupture of aneurysm | Fisher exact test | .082 |
| Grade of preinterventional CNP | Fisher exact test | .009 |
| Degree of aneurysm embolization | Fisher exact test | .391 |
| Aneurysm location | Fisher exact test | .588 |

The degree of initial CNP was the only statistically significant prognostic factor concerning the final outcome, resulting in better recovery in case of incomplete initial CNP.
