Significances were calculated with independent samples t-test or Mann-Whitney test, according to the distribution. Normality of the distributions was checked using Shapiro-Wilk test. Data are presented as mean and standard deviation (SD) with normal distribution (a on the upper corner of the variable) and median, minimum, maximum with non-gaussian distribution (b on the upper corner of the variable); 95% CIoD: 95% Confidence Interval of the Difference (lower-upper). Categorical variables were described using frequency (case number) and percentage
