Significant differences in DFS and RFS rates were found between subjects with mild/moderate and severe stenosis (<em>P <</em> 0.001). Significant differences in DFS rates were observed across Carotid Plaque–RADS categories (<em>P <</em> 0.001), with a notable decrease in DFS rates as Carotid Plaque–RADS categories increased from 1 to 4.
