Statistical analysis• Descriptive statistics.
• Due to a small sample size, a non-parametric test (Friedman test) was carried out to assess differences among groups. If a significant difference was found, post hoc comparisons among groups were performed using the Wilcoxon-Nemenyi-McDonald-Thompson test.
• The analysis was carried out by means of the R environment (The R Foundation for Statistical Computing).
• Data set and code employed for the analysis can be found at www.figshare.com (*).*http://dx.doi.org/10.6084/m9.figshare.977866
