	AUC	Test + Criterion	Sensitivity	Specificity	PPV	NPV	Accuracy
PSR _E	0.88	< 6.65	89%	74%	77%	87%	81%
Percentage sweep volume recovery, early diastole	0.82	< 57.90	65%	87%	83%	71%	76%
Normalized average sweep rate, early diastole	0.93	< 3.12	85%	87%	87%	86%	86%
PSR _E /PSR _A	0.88	< 1.17	84%	81%	81%	83%	82%
DT _SV	0.83	> 100.89	82%	74%	76%	81%	78%
DSVRT ₅₀	0.79	> 19.45	63%	84%	80%	69%	73%

Classification performance results based on receiver operating characteristic (ROC) analysis. Threshold based on value yielding the greatest classification accuracy.
PSR_E = normalized peak sweep rate in early diastole; PSR_A = normalized peak sweep rate in atrial systole; DT_SV = sweep volume deceleration time; DSVRT₅₀ = 50% diastolic sweep volume recovery time; AUC = area under the curve; PPV = positive predictive value; NPV = negative predictive value.
