Continuous and normal data are presented as the mean ± standard deviation; continuous and non-normal data are presented as the median ± interquartile range. ^†, the correlation coefficient of morphological and FEA-derived parameters is >0.7. FEA, finite-element analysis; NWI, normalized wall index; MWT, maximal wall thickness; MPT, maximal plaque thickness; FCTmin, minimum fibrous cap thickness; FCTave, average fibrous cap thickness.
