Primes

• Blinding
  • The Verification invariant is operationalized by the blinding index: at study end, ask patients and assessors to guess their arm; guessing significantly better than chance means the channel leaked

    This sourceIntroduces the blinding index: at study end participants and assessors guess their arm, and guessing better than chance signals the concealment channel leaked (often via a telltale side effect).

Verification

Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.

Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
