Figure 1. Scatter plot comparison of human donor ages between MGS stages.

Figure 1

A horizontal bar indicates the mean age for each group. MGS 4 donors were significantly older than any other category of donors (one-way ANOVA, p < 0.005 and the Tukey-Kramer post-hoc test). The differences between stage 1–3 means were not significant.
