§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 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.
Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective. The Institute publishes certainty ratings and never recommendations. No telephone number, messaging handle or ordering channel appears anywhere on this site.
