Yoon, Il-Young Oh, Chang-Hwan Yoon, Jung-Won Suh, Tae-Jin Youn, In-Ho Chae, Dong-Ju ChoiLesions with smaller post-PCI MLDs and SERs had significantly higher risks of ISR. Lesions with post-PCI MLDs ≤2.4 mm and SERs ≤70% were at the highest risk of ISR, with an odds ratio of 23.3 (95% confidence interval, 2.74–198.08) compared with lesions with larger MLDs and SERs. There was a significant interaction between post-PCI MLD and SER (p = 0.038) on ISR.
