§2.3Population

Indication. Type 2 diabetes mellitus

A disorder of glucose regulation characterised by insulin resistance with relative insulin deficiency, diagnosed by glycated haemoglobin, fasting plasma glucose or oral glucose tolerance criteria.

Geographic footprint. Germany · Norway · Finland · Italy · Hungary · New Zealand.

§2.4Eligibility as the Institute reads it

  • Included. A disorder of glucose regulation characterised by insulin resistance with relative insulin deficiency, diagnosed by glycated haemoglobin, fasting plasma glucose or oral glucose tolerance criteria.
  • 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.
