  1. 1. Chi-square test
  2. 2. Median and 25th and 75th percentiles; Kruskal-Wallis test for multiple groups.
  3. 3. Dunn test for multiple comparisons for the variable "duration of symptoms"
  4. - p < 0.05: (≤ 6.0 months) × (6.1 - 12.0 months);
  5. - p < 0.05: (≤ 6.0 months) × (12.1 - 24.0 months);
  6. - p < 0.05: 6.1 - 12.0 months) × (12.1 - 24.0 months);

  8. Digestive symptoms: ≤ 6 months versus 6-12 months, p = 0.008; ≤ 6 months versus 12-24 months, p = 0.005; 6-12 months versus 12-24 months, p = 0.737.
