a Dichotomous variables. Results are presented as number of individuals and (percentage from the sub-group). p value was calculated using chi-square test.

b Numerical variables with non-parametric distribution. Results are presented as median and [interquartile range]. p value was calculated using Mann-Whitney U test.

c Numerical variables with Gaussian distribution. Results are presented as average ± standard deviation. p value was calculated using unpaired t-student test.
