Baseline data of 106 patients were stratified into four quartiles according to plaque CXCL10 concentration. †Values are represented as mean ± SD or median (Inter Quartile Range) as appropriate. *P values based on ANOVA test between CXCL10 quartiles for continuous variables and nonparametric Mann-Whitney test for categorical variables.
