Patient Characteristics Associated with Dyspnea Improvement by Visual Analog Scale

Model Scale	Variables	AOR	95% CI	p-value
VAS	Baseline dyspnea^*	1.55	(1.36–1.77)	<0.001
7 point Likert	Jugular venous distention	0.46	(0.28–0.77)	0.003

N = 311; c-index = 0.756

For each 1 point change by the VAS. Patients who could not improve 3 points at baseline were excluded.

AOR=adjusted odds ratio; VAS = visual analogue scale
