Table 4.

Average relative errors (in %) of the numerical pulse waveforms over all 70 measuring sites, and over all the sites in the aorta and the vessels of the first, second and third generation of bifurcations. Single errors were calculated as described in Table 2. The standard deviation is given for each error. The probability p of the two-sample t-test is given for the average errors over all 70 measuring sites assuming equal variances.
