  1. Values for all investigated parameters are given at six measurement contours in the aorta are given. Results of all three groups were tested for significance using Kruskal-Wallis-Test (all). In the column on the far right all three groups were tested in pairs (SP vs. TP, SP vs. Healthy, TP vs. Healthy, respectively) by means of Man-Whitney-U-Test. Significant differences are marked in bold type
