§1Evidence extract: Inflammatory bowel disease and mucosal barrier disorders

§1.1Question and anchor outcome

Population
Chronic immune-mediated inflammation of the intestinal tract, or disorders of intestinal permeability including coeliac disease.
Intervention
Larazotide acetate, oral, before meals
Comparator
As used in each contributing trial; reported per trial rather than pooled across comparator types
Anchor outcome
Clinical remission

Additional outcomes the Institute extracts for this indication: Endoscopic healing; Faecal calprotectin; Intestinal permeability by lactulose–mannitol ratio.

Figure 2. Domain-by-domain certainty assessment for Larazotide acetate in inflammatory bowel disease and mucosal barrier disorders. The starting rating for a body of randomised evidence is high; each serious concern reduces it by one level and each very serious concern by two.

Table 2. Reasoning recorded against each certainty domain.

DomainRatingReasoning
Risk of biasNo concernNo serious concern identified in this domain.
InconsistencyNo concernNo serious concern identified in this domain.
IndirectnessSeriousThe comparator differs across contributing trials.
ImprecisionNo concernNo serious concern identified in this domain.
Publication biasNo concernNo serious concern identified in this domain.
Overall rating: Moderate certainty. The true effect is likely to be close to the estimate, but there is a possibility that it is substantially different. Further research is likely to have an important impact on confidence in the estimate.
