Table 2. Influenza- and Respiratory Syncytial Virus–Attributable Cardiorespiratory Hospitalizations^a .

Age group, y	Attributable events, No. (95% CI)	Person-years, No.	Attributable event rate per 100 000 person-years, No. (95% CI)
65-74	741 (415-1067)	783 660	95 (53-136)
75-84	2345 (1795-2896)	1 640 294	143 (109-177)
≥85	7852 (7204-8501)	2 655 918	296 (271-320)
Total	10 939 (9413-12 464)	5 079 872	215 (185-245)

^a Final negative binomial regression model was used to estimate hospitalizations. Estimates for each age group were rounded to the nearest whole number and thus may not perfectly reflect the sum total.
