double dummy

double dummy

A technique for retaining the blinding of a clinical trial, where the two treatments cannot be made identical. Supplies are prepared for Treatment A (active and indistinguishable placebo) and for Treatment B (active and indistinguishable placebo); subjects then take two sets of treatment, either A (active) and B (placebo), or A (placebo) and B (active).
