Functional connectivity (Pearson correlation) was calculated for each pair of ROIs to create connectivity matrix for each subject. For every edge, a multiple regression was performed with connectivity as the dependent variable and MBI‐C, MoCA, and UPDRS‐III as the predictor variables. Significant edges were determined if the overall model had a significance of p < .05 with a FDR correction. Each resulting significant edge was then used in the commonality analysis
