Boxplot diagram analyzing the differences in the "add-up score" calculated from maximal signal intensity, upslope and time to 50% of the maximal signal intensity between native vessels (native) and bypass grafts (CABG), also distinguishing between LIMA and venous grafts. There is no tendency towards negative results (the more negative the score the smaller the upslope, the longer the time to 50% of maximal signal intensity (T50%SImax) and the smaller the maximal signal intensity (SImax)); therefore no add-up effect of these parameters can be demonstrated.
