CI = confidence interval; OR = odds ratio; other abbreviations as in Tables 2 and 3.

  • In addition to patient-level variables, models were adjusted for the following lesion-level covariates: TCFA, ThCFA, fibrotic plaque, EEM CSA, luminal CSA, plaque + media CSA, dense calcium CSA, and percentage dense calcium volume.

  • Dependent outcomes were percentage necrotic core volume > median (10%) and percentage fibrous tissue volume > median (60%).
