Table 2. Reclassification of 10-year risk by adding CIMT to FRS-type model.

10-year risk in model with standardized CIMT in participants
without incident stroke (non-cases)
10-year risk in model
without standardized CIMT 		0-5% 5-10% 10-20% ≥20%
0 - <5% 307 19 0 0
5 - <10% 129 1370 195 0
10 - <20% 0 278 874 167
≥20% 0 0 134 429
NRI non-events=0.041 541 = reclassified into lower risk 381 = reclassified into higher risk
10-year risk in model with standardized CIMT in participants with
