aANOVA is used if nothing else i stated. bStudents paired T-test is used if nothing else is stated. A significant difference (p < 0.05) is indicated with”<” or “>”. cPost-Anova tests were only performed in outcome variables were a statistical significant difference was observed in the primary ANOVA test. dKruskal Wallis Ranksum test. eWilcoxon matched paired Rank test. ¤ A mean value has been calculated despite of the categorical nature of this variable
