Assignment to clusters based on the clinical algorithm shown in Figure 2 was compared to the correct cluster as generated through full data analysis. For example, the clinical algorithm appropriately classified 91.8% of patients in Cluster 1 to Cluster 1, whereas 6.1% were incorrectly assigned to Cluster 2, 2.0% to Cluster 3, and none to Cluster 4 or 5.
