Correlation values of the two components from the testing dataset (visit 1, visit 2 and combining visits 1 and 2) that exhibit the highest correlation with the selected RSNs from the model dataset are shown.

^aIn the visit 1 testing dataset, the same component had the highest spatial correlation with the primary visual and posterior cingulate DMN networks of the model dataset.

ICA, independent component analyses; RSNs, resting state networks; DMN, default mode network.
