Values are means ± standard deviations in interval variables, frequencies (relative frequencies) in categorical variables and median (interquartile range) in ordinal variables. p for difference between the two categories were calculated using Student t test and Fisher’s two-sided exact test, or Wilcoxon two-sided test, respectively. Significant differences are marked in bold
