Masking
Double-blind (participant, investigator and sponsor)
Arms
4
Allocation
Randomised across dose arms and a common comparator
Endpoint adjudication
Not applicable to the primary endpoint of this design
Data monitoring
As specified in the protocol

§2.2Arms

Table 2. Randomised arms. Illustrative: arm-level allocations are reconstructed by the Institute from the design class and the randomised total where the published report does not state them.

The randomised total is not recorded by the Institute and arm-level figures are therefore not presented.

§2.3Population

Indication. Cutaneous wound healing and tissue repair

Restoration of epithelial and dermal integrity following injury, assessed by closure rate, area reduction and scar quality.

§2.4Eligibility as the Institute reads it

  • Included. Restoration of epithelial and dermal integrity following injury, assessed by closure rate, area reduction and scar quality.
  • Excluded. Participants for whom the intervention is contraindicated, including wilson disease or any disorder of copper handling would be an absolute contraindication…. 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.
