In contrast, native jugular veins showed a clear, dose-dependent relaxation, reaching highly significant differences at the maximal concentration ( p < 0.0001 vs. all graft groups; Fig. 2 A).

TiProtec-treated grafts showed the largest diameters, although this difference did not reach statistical significance compared with NS- or DuraGraft-preserved grafts.
