Fig. 5: Correlations of post-central cortex FC with clinical scores.

Scatterplots of the Unified Parkinson’s Disease Rating Scale Motor Examination score (UPDRS-ME, a, p = 0.007) and Hoehn and Yahr stage (H&Y, b, p = 0.002) against the mean FC of the regions where the post-central cortex FC correlates with pPDU (highlighted in the inserts on the right, the most affected side is at reader’s left). For each graph, residuals from the linear regression analysis, following correction for age sex and motion parameters, are plotted. Regression line along with the 95% confidence intervals is superimposed.
