^aContinuous variable, two-way ANOVA is adopted, and mean ± SD is used for statistical description; the unit is seconds.

^bThere is an interaction between population grouping and BMI grouping after correction by Bonferroni method. SCWT, the Stroop Color-Word Test.

The two-way ANOVA was carried out with age, gender, and years of education as covariates.
