Clinical confirmation of biochemical results. Distribution of clinical data: fiber length (A), nerve density (B), number of nerve ramifications (C) and diameter (D) of nerve fibers. Data are visualized as bean plots where the polygon shape (in black line and light blue filling) represents the density trace computed using a log- transformation of each variable, instead a scatter plot shows each single NK patient used for the distribution (in black line).* means p < 0.05, and ** means p < 0.01 obtained by the Kruskal–Wallis test and Dunns’ post hoc test.
