Figure 2. Outcome comparison between the medical treatment and PCI groups in lesion subsets divided by HRP.

There was no difference in outcomes between the medical treatment and PCI groups in lesions with A) neither qn-HRP nor ql-HRP and B) either qn-hRP or ql-HRP, while C) the PCI group showed a better outcome in lesions with both qn-HRP and ql-HRP as compared with the medical treatment group. This analysis was done in the whole population (n=697). qn-HRP was defined as a lesion with an MLA <3.3 mm² and a plaque burden ≥70.0%, and ql-HRP as with low-attenuation plaque or positive remodelling. CI: confidence interval; HR: hazard ratio; HRP: high-risk plaque; MLA: minimum lumen area; NA: not available; PCI: percutaneous coronary intervention; ql-HRP: qualitative HRP; qn-HRP: quantitative HRP
