Table 10

Statistical analysis of the CBR classification considering 𝑘=1.

Criteria/indices	Values
Total cases	29
Not healthy (Class C) group (P)	8
Healthy (Class A + Class B) group (N)	21
True positive (TP)	6
False positive (FP)	1
True negative (TN)	20
False negative (FN)	2
Sensitivity = TP/(TP + FN)	≈0.75
Specificity = TN/(FP + TN)	≈0.95
Accuracy = (TP + TN)/(P + N)	≈0.90
