Table 3.

ROC curve co-ordinate results to determine the diagnostic accuracy of using LAAEF and LAEF to predict LVDD.

Predictor	AUC	P-Value	Sensitivity (%)	Specificity (%)	Predictor value for given sensitivity and specificity (%)
LAAEF	0.861	<0.01	79.7	82.9	≤38.5
LAEF	0.826	<0.01	72.5	73.2	≤52.5

AUC, area under curve; LAAEF, left atrial active emptying fraction; LAEF, left atrial ejection fraction.
