Figure 2.

Median neurite lengths with neurotrophic supplementation. The diagrams (A–D) show the fold change of the median neurite length of every explant regarding the median of the control group with different neurotrophic supplementations. The groups in the first graph (A) contain an equal number of samples from three turns, hence representing the whole cochlea. Diagrams (B–D) depict the individual turns. (A–D) The boxes extend from the 25% to the 75% percentile. The black bar denotes the median. The whiskers delimit the 1.5-fold interquartile range. Samples within this range are marked as grey dots, and samples beyond this range are black. A grey line marks the median of the control group. The number of samples in each group is written right below the X-axis. The asterisks or ns (not significant) above the groups indicate the significance level of a Kruskal–Wallis test followed by a Dunn’s multi-comparison post-hoc test against the control group. (E) Representative explants at the median of the best-performing groups in (A).
