Figure 2 Relationship Between Patency Score of the Grafts and Right Coronary Lesion Characteristics
Relationship between patency score of the analyzed grafts (saphenous vein grafts [SVG], right gastroepiploic artery grafts [GEA]) and minimum lumen diameter (top) and percent stenosis (bottom) of the grafted right coronary artery. The box ends are Tukey’s hinges; the whiskers are at the largest and smallest values that are not outliers or extremes, which are defined as 1.5 and 3.0 interquartile ranges from the hinges.
