Table 4. Validation analysis of u-FCMSS in the second cohort including MDS and non-clonal cytopenias diseases.

		Conventional diagnosis (clinical and morphologic diagnosis)
		MDS	Non-clonal cytopenias	Total
u-FCMSS diagnosis	MDS	78 (a)	3 (b)	81 (a+b)
	Non-MDS	12 (c)	42 (d)	54 (c+d)
	total	90 (a+c)	45 (b+d)

Sensitivity = [a/(a+c)]×100% = 86.7%.

Specificity = [d/(b+d)]×100% = 93.3%.

Positive predictive value = [a/(a+b)]×100% = 96.3%.

Negative predictive value = [d/(c+d)]×100% = 77.8%.

Diagnosis agreement rate = [(a+d)/(a+b+c+d)]×100% = 88.9%.
