Multiple Regression Analysis Models for Prediction of Postsurgical Outcome
| Independent variable | Postsurgical outcome class (R2 = 0.40; P = 0.004) | ||
|---|---|---|---|
| β | SE | P | |
| MRI* | 0.32 | 0.17 | 0.07 |
| PET† | 0.51 | 0.17 | 0.007 |
↵* MRI group 1: definite focal potentially epileptogenic lesion detected preoperatively; MRI group 2: no focal lesion detected.
↵† FDG PET group 1: focal localizing region of hypometabolism detected; FDG PET group 2: nonlocalizing findings.
R2 is for the model. β is standardized regression coefficient for each independent variable. SE is for each independent variable. Data are for the 24 patients who underwent epilepsy surgery.
