Table 2 Number of arteries with low or high maximal wall thickness parameters, stratified according to CCA plaque presence (Mannheim criteria). Using maximal wall thickness parameters as risk markers instead of Mannheim criteria results in reclassification of subjects towards another risk category. For example, the thickness-to-IMT ratio (right columns) reclassifies 70 and 25 subjects towards a higher and lower risk category, respectively, in total 26%
