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
