§2.3Population

Indications. Obesity and overweight in adults · Type 2 diabetes mellitus

Excess adiposity sufficient to impair health, operationalised in the pivotal incretin programmes as a body-mass index of 30 kg/m² or above, or 27 kg/m² or above with at least one weight-related comorbidity.

Geographic footprint. Canada · Belgium · Poland · Hungary · Japan · Australia · New Zealand · Argentina.

§2.4Eligibility as the Institute reads it

• Included. Excess adiposity sufficient to impair health, operationalised in the pivotal incretin programmes as a body-mass index of 30 kg/m² or above, or 27 kg/m² or above with at least one weight-related comorbidity.
• Excluded. Participants for whom the intervention is contraindicated, including personal or family history of medullary thyroid carcinoma. Exclusion criteria narrow the population to which the estimate applies and are the principal source of indirectness where a trial estimate is applied to ordinary practice.
