†Statistical difference between macroscopic grades of each group compared to control. ∗Statistical difference between macroscopic grades of each group compared to synthetic surgical mesh. Grade score = n∗G/N. n: number of rats with same grade score in each group; G: macroscopic score; N: total number of rats in each group.
