Table 2.

(a) Weight (µg) analysis of the three experimental membranes (Derma Fina, Evolution Standard and Duo-Teck) after immersion periods up to 21 days in PBS (Hydrolytic degradation test), collagenase from Clostridium histolyticum (Bacterial collagenase resistance test) and trypsin (Enzyme resistance test). Values shown are mean and standard deviation. (b) Attained p values after pairwise comparisons between membranes’ weights after the different immersion times and the initial weight (weight at t0: W0). Significance was considered at p ≤ 0.001.
