Table 1 Statistical significance of differences between friction coefficients measured under different experimental conditions (Two Way ANOVA and a Holm-Sidak multiple comparison post-hoc test).
Condition | Sliding direction | Significant difference |
|---|---|---|
dry | rostral versus caudal | yes (p < 0.001) |
dry | rostral versus lateral | yes (p < 0.001) |
dry | caudal versus lateral | yes (p < 0.001) |
wet | rostral versus caudal | yes (p < 0.001) |
wet | rostral versus lateral | no (p = 0.548) |
wet | caudal versus lateral | yes (p < 0.001) |
dry versus wet | rostral | yes (p < 0.001) |
dry versus wet | caudal | no (p = 0.198) |
dry versus wet | lateral | no (p < 0.705) |
