Figure 1

Illustration of required canonical discriminant functions to differentiate Clusters 1, 2 and 3. Two discriminant functions were identified that significantly differentiated the clusters accounting for 71% and 29% of the variance among them (Wilk's Lambda for Function 1: χ2 = 168.28, P < .0001; and for Function 2: χ2 = 59.10, P < .0001).
