Hospitalization by gender in propensity score matched heart failure patients

Cause-specific hospitalization	Rate, per 10000 person-years (events/total follow up years)		Absolute rate difference^* (per 10000 person-years)	Hazard ratio^† (95% confidence interval)	P value
Cause-specific hospitalization	Male (N=1669)	Female (N=1669)	Absolute rate difference^* (per 10000 person-years)	Hazard ratio^† (95% confidence interval)	P value
All cause	4003 (1114/2783)	3762 (1093/2905)	− 240	1.03 (0.93–1.15)	0.538
Cardiovascular	2491 (834/3348)	2570 (877/3412)	+ 79	1.10 (0.98–1.23)	0.121
Heart failure	1212 (489/4034)	1215 (510/4198)	+ 3	1.04 (0.90–1.20)	0.610
Myocardial infarction	194 (90/4638)	208 (101/4865)	+14	1.20 (0.86–1.66)	0.281
Unstable angina	528 (177/3350)	738 (252/3415)	+210	1.38 (1.11–1.72)	0.003
Stroke	202 (93/4598)	139 (68/4891)	−63	0.65 (0.46–0.92)	0.014
Other cardiovascular	416 (183/4403)	375 (175/4668)	−41	0.89 (0.70–1.12)	0.309
Non cardiovascular	1560 (589/3776)	1362 (550/4038)	−198	0.89 (0.78–1.02)	0.100

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

^†

Hazard ratios and confidence intervals (CI) (when women were compared to men) were estimated from matched Cox proportional hazards models
