Bacterial endotoxin in research-supply peptide presentations — amendment log
Every change made since protocol registration, with its date and reason.
§5Amendment log
Every change made to this review after protocol registration is recorded below with its date and its reason. A change that is not in this log did not happen. The Institute publishes the log in full, including changes that did not alter a conclusion, because a reader cannot judge which changes matter unless all of them are visible.

§5.2Clinical study report requests
Table 10. Clinical study reports requested for the contributing trials, and the outcome of each request. Refusals are recorded because a review that does not record them presents the sponsor's disclosure decision as the Institute's own.

§5.3Superseded versions
Superseded versions of this review remain published at a stable address, are marked as superseded, and link forward to the current version. The current version links back to each of them. That practice was adopted following a submission that a document cited in the literature must remain retrievable in the form in which it was cited; the reasoning is published on the corrections policy disposition page.
