Quantification of NF200-immunopositive axonal profiles at midgraft-level at 16 weeks post-surgery. ANG reconstructions revealed the highest numbers of NF200-positive axonal profiles among all tested implants. CorrCNG[F]s showed slightly increased numbers of immunopositive axonal profiles, when compared to the other artificial nerve guides tested. Kruskal–Wallis test [H(3, N = 28) = 7.74, p = 0.0517] followed by Dunn’s multiple comparisons were applied. No significant differences were detected. Values are given as mean ± SEM. ANG, autologous nerve graft; corrCNG[F], corrugated chitosan-film enhanced chitosan nerve guide: n = 8; CNG, chitosan nerve guide: n = 5; CNG[F], chitosan-film enhanced chitosan nerve guide: n = 7.
