Performance while varying the definition of LVEDP elevation and non-elevation.
a) the definition of elevation is held constant at ≥25mmHg, while the definition of non-elevation is varied from ≤12mmHg to ≤24mmHg, and the ROC curves assessed for each scenario. b) the definition of both elevation and non-elevation are varied from ≥13-25mmHg and ≤12-24mmHg, respectively, and the corresponding AUCs represented as a heatmap.
