Top: Comparisons between controls and patients with unilateral TLE. Asterisks and hash symbols indicated corresponding comparisons.
Bottom: Comparisons between patients with an excellent postoperative outcome (ILAE 1) and suboptimal outcome (ILAE 2+). Values are mean volume (mm3) (and SD).
F = main ANOVA value; P = significance level of corresponding comparison; sig = significance.
