| 1. Young people’s and parent's/carers’ perceptions and views regarding dietary therapy and on participating in research on dietary therapy assessed using interviews conducted at the end of the first week, end of week 6 and after completion of the intervention by week 13-14 2. Recruitment rate assessed using the number of screened young people who participate in the study 3. Retention rate assessed using the number of screened young people who complete the study 4. Acceptability and feasibility of the sugar permeability test and collection of stool, urine and blood samples assessed using the number of participating young people who provide samples of blood, stool and urine at baseline and 6 and 12 weeks 5. Intestinal inflammation assessed using calprotectin level in stool samples measured using ELISA at baseline, 6 and 12 weeks 6. Intestinal permeability assessed using urinary concentrations of lactulose, rhamnose and mannitol following oral administration, blood concentrations of endotoxin antibodies and intestinal fatty acid binding protein and faecal a1-antitrypsin measured using ELISA at baseline, 6 and 12 weeks 7. Systemic inflammation assessed using serum C-reactive protein level, erythrocyte sedimentation rate, a-1 acid glycoprotein level, cytokine assay (multiplex method) and blood platelets measured by haematology analyser at baseline, 6 and 12 weeks 8. Serum levels of growth factors, including insulin-like growth factor (IGF)-1 and IGF binding protein-3, measured using ELISA at baseline, 6 and 12 weeks 9. Disease activity measured using the weighted paediatric Crohn’s Disease Activity Index at baseline, 6 and 12 weeks 10. Quality of life assessed using a paediatric inflammatory bowel disease disease-specific health-related quality of life instrument - the IMPACT III questionnaire - at baseline, 6 and 12 weeks | — |
