Analysis of possible predictors of surgical outcome of MTLE
| Possible predictors | Favorable outcome group | Poor response group | P |
| ATL: Anterior temporal lobectomy, CPS: Complex focal seizures, FS: Febrile seizure; HS: Hippocampal sclerosis, SAH/SF: The sylian fissure approach of selective amygdalohippocampectomy, SAH/STS: The superior temporal sulcus approach of selective amygdalohippocampectomy, sGTCS: Secondarily generalized tonic-clonic seizure. *P < 0.05, Mann-Whitney U test. | |||
