Association between elevated jugular venous pressure (JVP) and hospitalizations^* in chronic heart failure, before and after propensity matching

Outcomes	Rate, per 10000 person-years (Events / total follow up years)		Absolute rate difference^† (per 10000 person-years)	Hazard ratio (95% confidence interval)	P value
Pre-match	Normal JVP (n = 6768)	Elevated JVP (n = 1020)

All-cause	3664 (4044 / 12019)	5186 (724 / 1396)	+ 1522	1.35 (1.25–1.47)	<0.0001
Cardiovascular	2402 (3416 / 14221)	3576 (594 / 1661)	+ 1174	1.42 (1.31–1.55)	<0.0001
Worsening heart failure	1086 (1888 / 17387)	1931 (399 / 2066)	+ 845	1.71 (1.53–1.90)	<0.0001

Post-match	Normal JVP (n = 827)	Elevated JVP (n = 827)

All-cause	5056 (583 / 1153)	4882 (578 / 1184)	- 175	0.97 (0.87–1.09)	0.613
Cardiovascular	3508 (483 / 1377)	3338 (470 / 1408)	- 170	1.02 (0.87-1.19)	0.841
Worsening heart failure	1890 (319 / 1688)	1813 (314 / 1732)	- 77	0.94 (0.78–1.14)	0.532

Data shown include the first hospitalization of each patient for each cause.

^†

Absolute differences in rates of events per 10,000 person-year of follow up were calculated by subtracting the event rates in the normal JVP group from the event rates in the elevated JVP group (before values were rounded).
