  1. Results were only presented for HAM-A and OCI-R. The number of overlaps (OL) is negligible compared to the total number of connections, as reflected by smaller values of the Jaccard index (JI). Each connection was given a weight based on the number of times it appeared in the leave-one-out bootstrap scheme for that group. Thresholding (as specified) was performed to select the connections that contributed most to the prediction. The overlap represents the number of connections that were common between the two groups.
