§2.3Population

Indication. Obesity and overweight in adults

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.

§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 not established — the compound has no marketing authorisation and therefore no approved…. 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.
