(1): Pearson’s correlation coefficicent; (2): Spearman’s correlation coefficicent; (3): ONE-WAY ANOVA; (4): post hoc test showed no statistical difference; (5): post hoc test showed the statistical difference between daily- seizure group and yearly-seizure in SF sub-scale; (6): post hoc test showed the statistical difference between seizure-free for one year group and drug-resistant group in QOL and CF sub-scales
