§1.2Consultation questions

The secretariat put the following questions. A submission was not required to address them and several did not; the questions record what the Institute was uncertain about rather than restricting what a respondent could raise.

  1. Is the high certainty rating for the anchor outcome correctly drawn from the contributing STEP and SURMOUNT trials?
  2. Should percentage weight change and categorical response at a threshold be reported as two anchor outcomes rather than one with a derived secondary?
  3. Are the limitations recorded in the abstract sufficient, in particular in relation to the sponsor concentration of the contributing evidence base?

§1.3How a submission is handled

  • Every submission is signed. The Institute publishes no anonymous submission.
  • Every submission carries a declared interest. A declaration of no interest is itself a declaration and is recorded as one. A declaration is not a disqualification and the Institute has never given a submission less weight on that ground.
  • A submission from an employee of a marketing-authorisation holder is identified as an industry submission on its face, following a unanimous consultation on the conflicts policy.
  • Every submission receives a secretariat response and a disposition. Submissions that are not accepted remain published in full; the Institute does not remove a submission because it disagrees with it.
  • There is no voting, no reputation score, no reply thread and no editing after receipt.

§1.4Outcome

The synthesis was amended before ratification. Percentage change and categorical response are now reported as separate outcomes with separate certainty ratings, and the concentration of the evidence base in sponsor-conducted trials is stated in the abstract rather than in the limitations annex.

The disposition table, listing each submission with its disposition and the resulting amendment, is at §3.

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.
