The confusion matrices of whole plasma, EV, and EV-free plasma microRNAs.

Whole plasma			EV			EV-free plasma
	Predicted granuloma	Predicted adenocarcinoma		Predicted granuloma	Predicted adenocarcinoma		Predicted granuloma	Predicted adenocarcinoma
Actual granuloma	21	6	Actual granuloma	19	8	Actual granuloma	8	19
Actual adenocarcinoma	7	23	Actual adenocarcinoma	12	18	Actual adenocarcinoma	0	30
Granuloma accuracy	21/(21+6) = 77.77%		Granuloma accuracy	19/(19+8) = 70.37%		Granuloma accuracy	8/(8+19) = 29.63%
Adenocarcinoma accuracy	23/(7+23) = 76.67%		Adenocarcinoma accuracy	18/(12+18) = 60.00%		Adenocarcinoma accuracy	30/(0+30) = 100.00%
Weighted accuracy	(77.77%+76.67%)/2 = 77.22%		Weighted accuracy	(70.37%+60.00%)/2 = 65.19%		Weighted accuracy	(29.63%+100.00%)/2 = 64.82%
