Discriminant regression analysis of the pulsed Doppler echocardiographic indices and group classification

Variable	Intercept	Coefficient	r2	p Value	AT	Sensitivity	Specificity
DWI	−6.143	2.638	0.3696	0.0004	83.33	80%	85%
TPSE	−6.357	0.336	0.3863	0.0002	76.67	80%	75%
PVDW	−8.211	57.220	0.3801	0.0003	83.33	80%	85%

AT, accuracy test (%); DWI, D wave integral; PVDW, peak velocity of the D wave; TPSE, tricuspid plane systolic excursion.
