Values are presented as mean±standard deviation or number (%). Chi-square test was used to detect the differences of categorical variables between different groups. One-way ANOVA was used to detect the differences of continuous variables between different groups. *p<0.05; **p<0.01; †pairwise comparisons were adjusted for multiple testing using LSD correction. ANOVA, analysis of variance; LSD, least significant difference; MMN, mismatch negativity
