Text: Protein adsorption was higher in group 1 and group 2 (group 1 vs. group 3, 2. 2 + / -0. 8 vs. 1. 4 + / -0. 3, P = 0. 01 ; group 2 vs. group 3, 2. 4 + / -0. 7 vs. 1. 4 + / -0. 3, P = 0. 02 ; group 2 vs. group 4, 2. 4 + / -0. 7 vs. 1. 8 + / -0. 3, P = 0. 04), it was also higher at group 4 when compared to group 3 (1. 8 + / -0. 3 vs. 1. 4 + / -0. 3, P = 0. 03).
