Presurgical factors and outcome in 74 MTLE patients (unifactorial analysis)*
| Factor | Number of patients (%) | |||||
|---|---|---|---|---|---|---|
| n | Class I & II | Class III & IV | p 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. | ||||||
