Double-Blind Study

Définition

A clinical trial design where neither the participants nor the researchers know who is receiving the active drug versus placebo. Double-blinding prevents both patient expectations and researcher bias from influencing the results.

Exemple

In a double-blind antidepressant trial, identical-looking pills are used so that neither patients nor doctors can distinguish the active drug from the placebo.
