  1. Data are presented as means ± SD or number (%)
  2. aThe two groups (adults and children) have different age ranges, so a t-test is not appropriate to compare their means
  3. bAll % calculated for 57 or 55 patients, respectively, unless stated otherwise. In case % were calculated for less than the maximal number of patients, data for some patients were missing and the actual denominator is displayed
