(A) Kaplan–Meier analysis. Subjects with a higher mean IMT (a) and a higher plaque score (b) showed significantly higher incidences of stroke. There were no significant differences in the incidence of coronary heart disease among subjects in different mean IMT groups (c) or in different plaque score groups (d). Subjects with a higher mean IMT (e) or a higher plaque score (f) showed significantly higher mortality rates. (B) Kaplan–Meier analysis for stroke. (a) Subjects with a higher IMT (IMT⩾0.7) showed a significantly higher incidence of stroke. (b) There were no significant differences in the incidence of coronary heart disease between subjects with a higher IMT and those with a lower mean IMT.
