Consultation on the draft of this analytical evidence review, which registers the question: How much does a reported chromatographic purity figure vary with the method used to obtain it?

§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.
- Is the high certainty rating for the anchor outcome correctly drawn from the contributing evidence?
- Is any eligible study missing from the included set, and is any included study ineligible under the registered criteria?
- Are the limitations recorded in the abstract sufficient, and is any material limitation omitted?
§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.
