Group comparisons were made to analyze possible correlations between gender, lesion type or single versus multiple AED use and PLI. Mann-Whitney U Test showed a significantly lower PLI in patients using multiple AEDs (M = 0.159) when compared to single AED use (M = 0.207). No correlation was found between lesion type or gender and PLI. The PLI difference for single versus multiple AED use remained significant after Bonferroni correction (p<0.025 as two comparisons were calculated).
