Population and applicability
Structured population data were available for 2 of 3 supporting studies. 1 study described participants with type 2 diabetes. 1 study described adult participants.
This population information refers to the materialized supporting studies available for review. Omitted support records remain part of the authoritative support accounting and are available through the audit experience.
View reported population descriptions
These descriptions are reported across the supporting studies; they are not a single synthesized population.
- Women diagnosed with type 2 diabetes.
- Women with non-alcoholic fatty liver disease.
- Adults aged 18-65 with obesity
- Individuals with elevated metabolic risk factors
Limitations
- 1 supporting study does not have a displayable topic-matched quantitative effect.
- Evidence uses heterogeneous comparison contexts: baseline_within_group, unknown_unresolved, usual_care.
- 1 supporting study lacks usable structured population information.
- 1 supporting study has high, serious, critical, unclear, or unavailable risk-of-bias information.
