SVM and radiologist classification performance assessment

	SVM				Radiologists
	Group I (single time point)	Group II (first time point analysis)	Group II (longitudinal analysis)	Group I (single time point)	Group II (first time point analysis)	Group II (longitudinal analysis)
Sensitivity (%)	86.49	100	85.71	75.7	60	70
Specificity (%)	75.00	91.67	100	68.9	78	90
Accuracy (%)	81.53	94.7	94.7	73.84	68	84.2

McNemar’s test, SVM vs radiologist classifications (p value): group I: p value = 0.041, group II (first time point analysis): p value = 0.034, group II (longitudinal analysis): p value = 0.025
