Was there significant difference in tip-deflection between the lancet (L) and the axi-symmetric bevels (AX1–3)?${}^{\text{a}}$.

^aEach pair of bevels (e.g. L vs. AX1) were tested using a two-sample, two-sided, Wilcoxon rank sum test, n = 5, 5% error rate, significance level was 0.017 (Bonferroni-corrected). Bolded entries indicate no statistical significance found between bevel pair (i.e. p $\ge$ 0.017).
