Correlation analysis between change of ALFF value before and after ASD in the right medial pulvinar of the thalamus or the right lobule IV, V of cerebellar hemisphere and clinical characteristics in MWoA individuals. After adjusting for age, sex, and PSQI scores in the GLM model, a significant negative correlation was found between the change of ALFF values before and after ASD in the right medial pulvinar of the thalamus and monthly headache days (A). Furthermore, a significant negative correlation was found between the change of ALFF values before and after ASD in the right lobule IV, V of cerebellar hemisphere and VAS scores (B). Dots represent individuals with MWoA. The blue regression line represents Pearson’s correlation coefficient. Grey shading represents the 95% confidence intervals of the partial correlations.
