Slide 3

Abstract Systematic review to assess efficacy of HT in paediatric FAP/IBS patients. Three RCT comparing HT to a control treatment were included with sample sizes ranging from 22 to 52 children. All trials showed statistically significantly greater improvement in abdominal pain scores among children receiving HT. Therapeutic effects of HT seem superior to standard medical care in children with FAP or IBS.

5. If the results of the review have been combined, was it reasonable to do so? Not combined Different outcomes Small numbers

Slide 14

What are the overall results of the review? More studies needed! Results not pooled NNT not expressed (outcome not binary) Therapeutic effects of HT seem superior to standard medical care in children with FAP or IBS.
