Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure is the percentage of children with >30% reduction in abdominal pain intensity after 8 weeks of treatment from baseline. Abdominal pain intensity is measured daily for 7 consecutive days using an abdominal pain app. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome measures are other recently internationally defined outcome measures for trials in children with chronic abdominal pain: degree of reduction in pain frequency and pain intensity, percentage of patients with an adequate improvement in complaints, school absenteeism hours, quality of life, feelings of anxiety & depression, defecation pattern, taste, ease of use and side effects of the treatment. In addition, genetic polymorphisms associated with susceptibility to placebos are investigated and related to both primary and secondary outcome measures. | — |
