Data are presented as number (percentage) or mean±SD. P values were calculated using t test for continuous variables and Fisher exact test for categorical variables. MLA indicates minimum luminal area; MLD, minimum luminal diameter; OCT, optical coherence tomography; PCI, percutaneous coronary intervention; PR, plaque rupture.
