Table 3. Reclassification of 10-year CVD risk by adding CIMT to FRS-type model.

10-year risk in model with standardized CIMT in participants
without CVD (non-cases)
10-year risk in model
without standardized CIMT 		0-5% 5-10% 10-20% ≥20%
0 - <5% 0 0 0 0
5 - <10% 0 1 0 0
10 - <20% 0 2 369 67
≥20% 0 0 180 2255
NRI non-events=0.040 182 = reclassified into lower risk 67 = reclassified into higher risk
10-year risk in model with standardized CIMT in participants with
CVD (cases)
10-year risk in model
