  1. Data are expressed as mean and standard deviation for continuous variables (i.e. age) and as number of patients per each group for categorical variables (i.e. gender).
  2. The p-values refer to ANOVA and post-hoc comparisons with Bonferroni corrections for continuous variables, to χ2 for categorical variables.
