2.8. Statistical Analysis
The distribution of continuous variable was verified with Shapiro–Wilk test. As the majority of variables were significantly different form normal distribution, they were presented as medians (M) and interquartile ranges (IQR). Qualitative data were expressed as numbers and percentages. To test whether the allocation procedure resulted in differences in gathered data, Mann–Whitney/Kruskal–Wallis or chi2/Fisher’s exact test were used when appropriate. To evaluate the interaction between tested groups allocation and faculty, two-way ANOVA was used; however, data were ranked, if necessary, to conform to normality. The level of significance was set as
