Table 3. Cardiovascular disease risk classification comparing the Framingham risk score at baseline with the Framingham risk score at the second health examination in the EPIC-Norfolk cohort (n = 12,197).

Individuals who developed cardiovascular events
	Framingham risk score at the 2nd health examination
	< 10.0%	10.0–19.9%	≥ 20.0%
Framingham risk score at baseline				Total
< 10.0%	95	57	2	154
10.0–19.9%	30	230	145	405
≥ 20.0%	3	68	741	812
Total	128	355	888	1,371
Individuals who did not develop cardiovascular events
	Framingham risk score at the 2nd health examination
	< 10.0%	10.0–19.9%	≥ 20.0%
Framingham risk score at baseline				Total
< 10.0%	3,994	1,060	41	5,095
10.0–19.9%	330	2,034	886	3,250
≥ 20.0%	13	312	2,156	2,481
Total	4,337	3,406	3,083	10,826

Note: The net reclassification improvement was 4.8%, p = 0.99
