Figure 5 Secondary outcome variables. Balloon‐to‐artery (B:A) ratio and prestent lumen diameter (LD) plotted against immediate lumen diameter gain (A, B), absolute stent recoil (C, D), minimum lumen cross‐sectional area (CSA) (E, F), late lumen loss (G, H) and late‐loss index (I, J). Other details are as in fig 4. Because of a single very large late‐loss index value of 48.5 for one vessel, the multilevel regression analysis and the within‐animal correlation analysis reported in I and J were performed with the outlier removed. A larger B:A ratio was associated with greater immediate lumen diameter gain (A), greater absolute stent recoil (C), greater late lumen loss (G) and lower late‐loss index values (I). A larger LD was associated with larger minimum lumen cross‐sectional area (F).
