Table 6

Breath classification for IPF versus PN and IPF versus CHF using individual and aggregate crackle features. The model was created using NNs and voting over classifications of individual crackles in a breath.

	Crackle and distribution
	Sensitivity	Specificity	Accuracy
PN	0.76	0.87	0.86
CHF	0.78	0.89	0.88
