HFNet predictive value. (A) Specificity vs Sensitivity on the entire internal holdout set; (B) PPVs on the subcohort of the internal holdout set with reduced Ejection Fraction (EF < 40) and as a function of CXR findings on present on presentation. CXR(edema +) = evidence of interstitial edema; CXR(edema −) = interstitial edema absent; CXR(redistribution +) = evidence of pulmonary vascular redistribution; CXR(redistribution −) = no pulmonary vascular redistribution noted. Prevalence of different CXR findings in patients with reduced LV function taken from reference 18 . Plots show mean and standard deviation over 10 bootstraps.
