| Lipid core CSA (%) | 6.6 (6.9) | 15.1 (7.6) | 22.1 (6.3) | <0.0001 |
Data are mean (SD).
Percentage stenosis of the MLA site is calculated as vesselareaMLA − lumenareaMLA/vesselareaMLA ×100. Remodelling index (RI) is defined as MLA of the external elastic membrane (EEM) cross sectional area (CSA)/reference EEM CSA.
