CP and carotid plaque build: The 2 and 3-year LT-free survival rates were 95.0% and 95.0% for patients with CP-A, 91.2% and 83.2% for those with CP-B and 78.7% and 72.7% for those with CP-C, respectively, and there were no significant differences in LT-free survival rates (CP-A vs. CP-B; p = 0.678, CP-A vs. CP-C; p = 0.281, CP-B vs. CP-C; p = 0.191) (Fig. 1B).
