Differences between groups were evaluated by log-rank statistics.
Differences in responses between groups were evaluated using analysis of variance (ANOVA).
Differences between groups were evaluated using parametric or non-parametric test as appropriate (χ2 or Fisher's test for categorical variables, and analysis of variance or Mann–Whitney U-test).
For the statistical analysis of the neural growth cone results, the differences between groups were evaluated using the Kruskal-Wallis test (non-parametric) followed by Dunn's multiple comparison test, as the data were not normally distributed.
The differences between groups were evaluated with independent sample t tests.
Differences between groups were evaluated using 2-way ANOVAs on log-transformed data.
Categorical variable differences between groups were evaluated using separate Pearson chi-squared tests.
BMI and age differences between groups were evaluated with a non-paired t test.
Comparisons between groups were evaluated by two-sided Student's t test or one-way analysis of variance.
Differences between groups were evaluated by unpaired Student's t test; intra-group variations were studied using paired Student's t test.
Individual comparisons between groups were evaluated post hoc using the Mann-Whitney test with Bonferroni adjustment for multiple testing.
