Reported

Institute-constructed programme record. This document is not a report of a published trial. It is a record the Institute has constructed to represent an instalment, sub-study or extension of a real development programme, published in order to carry a methodological point that the parent trial report does not address. No effect estimate on this page is attributable to any publication, and its reference-list entry carries a programme-record label rather than a citation. The policy governing these records was settled through a public comment period.

§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.

ArmAllocatedShareDescription
Thymosin beta-4Intervention at the dose reached after titration
PlaceboMatched placebo, administered on the same schedule
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.

Geographic footprint. Germany · Netherlands · France · Japan · China.

§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 not established — no marketing authorisation. 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.
