  2. bModel 1 was adjusting for age, sex, BMI, and diabetes mellitus
  3. cModel 2 contains model 1 with further adjustment for maximum NWI
  4. dIncrement of 10%; OR: odds ratio; WT: wall thickness; NWI: normalized wall index; LRNC: lipid-rich necrotic-core; IPH: intraplaque hemorrhage; CA: calcification
