In results section, the compliance -axis in Figure  6 had wrong values and now it is correct; furthermore, Table  1 representing median and percentile values of parameters reported in Figure 6 is added.

The correct text for the paragraph is as follows.

3.5. Mechanical Testing Results. The mechanical testing analysis (Figure  6, Table  1) resulted in no statistically significant differences for Young’s modulus, compliance, ultimate circumferential stress, burst pressure, and suture retention strength; on the other hand, there was a significant loss in ultimate strain between native and decellularized vessels; moreover, residual stress after relaxation was increased for decellularized samples compared to native ones.
