Figures
- FIG 1.
Frequencies of epileptogenic lesions stratified by etiologic categories.
- FIG 2.
Percentages of children with epileptogenic lesions stratified according to seizure types and the presence or absence of developmental delay. GTC indicates generalized tonic-clonic seizures.
- FIG 3.
Recursive partition analysis stratified children into 4 groups based only on the presence of DD and seizure types. GTC indicates generalized tonic-clonic seizures.
