Increased proportion of scar in lateral versus septal segments across CMR circumferential strain quartiles. The figure shows an increased proportion of scar in group 1 (lateral) segments versus group 2 (septal) segments based on the analysis of all 156 myocardial segments. This effect was consistent across all lower three CMR quartiles of Ecc, indicating that there is increased prevalence of segmental scar at any level of segmental Ecc in group 1 (lateral) segments versus group 2 (septal) segments. In other words, the association between depressed Ecc and scar has a significant regional dependence, with dysfunctional lateral segments much more likely to have scar than dysfunctional septal segments. 1^st quartile = least negative Ecc (most dysfunctional); 4^th quartile = most negative Ecc.
