Epidemiology: Blinding in Experimental Studies

Single blinding: when the patient does not know if he/she is getting the drug or placebo

Double blinding: where the patient and the dispensing doctor also does not know whether the patient is getting the drug or placebo

Triple blinding: where the patient, dispenser and the person analyzing the data also does not know the identity of the groups as the ‘therapy’ or ‘placebo’.
