LDA classification accuracies using a leave-one-out routine for three features: AP-area, PPT area and IH33.

	AP-area & IH33	AP-area & PPT area	AP area, PPT area and IH33
PCS (no depression) vrs. Control	100%	94%	94%
PCS & mild depression Vrs. Control	90%	83.3%	90%
PCS & moderate/SEVERE depression Vrs. Control	83%	93.6%	89.4%

Testing accuracy of two and three features combination for separating each of the three PCS groups (PCS & no depression (n = 18), PCS & mild depression (n = 27) and PCS & moderate/severe depression (n = 14)) from healthy controls (n = 33).
