Correlation matrix between mean track density measurements and MAPP symptom scores in UCPPS patients, localized to ROIs identified as different between UCPPS and HCs on statistical parameter maps.

<p>Dendrograms on the left side of the correlation matrix show hierarchical clustering of ROIs based on the association between track density measurements and symptom scores. Images showing ROI localization are chosen for select associations. Up arrows within cells denote significantly positive correlations (<i>P<0</i>.<i>05</i>) and down arrows within cells denote significantly negative correlations (<i>P<0</i>.<i>05</i>). (Note the level of significance was not corrected for multiple comparisons in this exploratory analysis).
