IQR: Interquartile range; SD: Standard deviation; χ2: Chi-square test; MC: Monte Carlo; F: F for ANOVA test, Pairwise comparison bet. each 2 groups was done using Post Hoc Test (Tukey); p: p value for comparing between the studied groups; p1: p value for comparing between negative CTA cases and positive CTA cases; p2: p value for comparing between negative CTA cases and positive CTA without previous intervention; p3: p value for comparing between positive CTA cases without previous intervention and post-stent/CABG
