 Presurgical factors and outcome in 74 MTLE patients (unifactorial analysis)*

FactorNumber of patients (%)
nClass I & IIClass III & IVp Value
*See outcome data for explanation of Engel categories. Classes I and II combined represent satisfactory outcomes, whereas Classes III and IV together represent unsatisfactory outcomes. Statistical analyses were done with Fisher’s exact test. Comparison of p values: factor present compared to factor not present. A p value of <0.050 indicates statistical significance; a p value 0.050–0.10 indicates a trend.
