§1Evidence extract: Metabolic dysfunction-associated steatohepatitis

§1.1Question and anchor outcome

Population
Steatotic liver disease with histological evidence of hepatocyte ballooning and lobular inflammation occurring in the context of at least one cardiometabolic risk factor. Formerly termed non-alcoholic steatohepatitis.
Intervention
Retatrutide, subcutaneous once weekly
Comparator
As used in each contributing trial; reported per trial rather than pooled across comparator types
Anchor outcome
Resolution of steatohepatitis without worsening of fibrosis

Additional outcomes the Institute extracts for this indication: Improvement of fibrosis by ≥1 stage without worsening of steatohepatitis; Change in liver stiffness by vibration-controlled transient elastography; Change in ALT.

Figure 2. Domain-by-domain certainty assessment for Retatrutide in metabolic dysfunction-associated steatohepatitis. 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.
ImprecisionSeriousThe confidence interval spans values that would support different decisions.
Publication biasNo concernNo serious concern identified in this domain.
Overall rating: Low certainty. Confidence in the effect estimate is limited. The true effect may be substantially different from the estimate.
