The classification accuracy (%) of the RF, LDA, and SVM that obtained the highest accuracy in phase I compared to after using the three search strategies of the hybrid FS approach (phase II of the proposed diagnostic tool).

Classifier	Before FS	Forward	Backward	Bidirectional
RF	90.88	91.6	91.33	90.93
LDA	90.35	91.07	91.07	91.33
SVM	90.43	90.58	90	90.53
