Table 2.

Classification of patients with different groups (normal, Gleason score ≤ 7 and Gleason score > 7)

Observed patients	Predicted patients	Normal	Gleason score ≤ 7	Gleason score > 7	% of correct classification
Normal (n = 25)		25	0	0	100
Score ≤7 (n = 16)		0	16	0	100
Score >7 (n = 7)		0	1	6	85.8
Total		25	17	6

This table represents a learning group and represents 75% of patients. The percentage of correctly classified patients corresponds to the ratio of the number of patients well classified by the total number of patients (n). It is observed that there is one individual of Gleason score >7 group is misclassified. The number in bold corresponded to patients well classified.
