Comparison of varicosity mean cross-sectional areas was performed using one-way ANOVA plus T3 Dunnet's multiple comparisons as a post hoc test to identify significant interactions. Two-sample K-S was used to compare size distributions of varicosities between different structures. Data from L5b, L6a, and L6b S1BF were previously published by Hoerder-Suabedissen et al. (2018).
