Association between baseline mitral regurgitation and presence of pulmonary hypertension (PHTN) (defined as pulmonary systolic pressure 36 mm Hg or higher)

	Mitral regurgitation at baseline
	None	Trace	Mild	Moderate	Severe
Total	1804	3011	624	253	51
PHTN present (n)	12	59	36	32	11
PHTN absent (n)	1792	2952	588	221	40
PHTN (%)	0.67	1.96	5.77	12.65	21.57
OR for PHTN	1	2.7 (1.4–5.0)	7.6 (3.9–15)	15 (7.4–30)	28 (12–69)

Odds ratio (OR) for PHTN was derived by multiple logistic regression with (95% CI), adjusting for age and gender. Shown are both numbers (n) and percent (%) with PHTN.
