Figure 1. Documents ratified in each assessment cycle. The first cycle carries the founding backfill, in which the Institute admitted the existing trial literature to its register in a single sitting; every cycle after it reflects ordinary quarterly work. The volume in the current cycle reflects the annual re-examination of the bibliography, the glossary and the register, which fall due together.

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.
