Effects of varying the similarity threshold to explore the temporal progression of patients. Here, patient groups and a portion of their corresponding tracking graphs are shown at 30, 34, 35, and 38 similarity thresholds. The focus time step of the tracking graphs is indicated with a black arrow, and the nodes are scaled based on the patient group’s size. In each graph, patient progression for 10 time steps both forward and backward in time from the focus time step is displayed.
