Domain-by-domain assessment of the certainty of the evidence this trial contributes.

§4.1Reasoning by domain
Table 6. Certainty domains, the rating recorded against each, and the reasoning.
| Domain | Rating | Reasoning |
|---|---|---|
| Risk of biasLimitations in the design and conduct of the contributing studies. | No concern | No serious concern identified in this domain. |
| InconsistencyUnexplained heterogeneity of results across contributing studies. | No concern | No serious concern identified in this domain. |
| IndirectnessDifferences between the population, intervention, comparator or outcome studied and those of the assessment question. | No concern | No serious concern identified in this domain. |
| ImprecisionWidth of the confidence interval relative to the decision threshold, and the number of events. | No concern | No serious concern identified in this domain. |
| Publication biasRisk that results were selectively reported or that unpublished studies exist. | No concern | No serious concern identified in this domain. |
§4.2Sponsorship
Manufacturer-sponsored. The Institute does not downgrade certainty for sponsorship as a separate domain, because doing so would double-count risk of bias as conventionally assessed. It records sponsorship on the front matter of every trial abstract, and treats the uniformity of sponsorship across this compound class as a limitation of the evidence base rather than of any individual trial. The reasoning is set out in the methodological review of sponsor-generated evidence.
