Fig. 5From: Alterations in regional homogeneity and multiple frequency amplitudes of low-frequency fluctuation in patients with new daily persistent headache: a resting-state functional magnetic resonance imaging studyCorrelation analysis between ALFF (0.027–0.073 Hz) z score and clinical characteristics. A-F Correlation analysis between ALFF (0.027–0.073 Hz) z score and pain intensity, disease duration, HIT-6 score, GAD-7 score, PHQ-9 score, and PSQI score. There was no significant difference after Bonferroni correction (p < 0.05/18). Dots represent patients with NDPH. The red regression line represents Pearson’s correlation coefficient (r). Grey shading represents the 95% confidence intervals of the partial correlations.
