Incidence of cardiovascular disease: stratified by decade of life and 12-year follow-up after examinations 1, 3, and 6 in Framingham Offspring Study participants

	Examination 1 (1971–1982)			Examination 3 (1983–1994)			Examination 6 (1995–2006)
Age, years	N	Number of cvd events	KM incidence rate	N	Number of CVD events	KM incidence rate	N	Number of CVD events	KM incidence rate
40–49	1405	148	10.7%	1236	84	6.9%	552	42	7.8%
50–59	501	88	18.0%	1060	139	13.6%	1168	121	10.9%
60–69	37	10	29.3%	481	99	21.7%	908	160	18.9%

Age grouped by decade at start of 12-year follow-up period following examinations 1, 3, and 6. CVD = cardiovascular disease; KM = Kaplan-Meier.
