Detailed explanation-1: -Double-blind trials are seen as the most reliable type of study because they involve neither the participant nor the doctor knowing who has received what treatment. The aim of this is to minimize the placebo effect and minimize bias.
Detailed explanation-2: -In a single-blind study, only the participants are blinded. In a double-blind study, both participants and experimenters are blinded. In a triple-blind study, the assignment is hidden not only from participants and experimenters, but also from the researchers analyzing the data.
Detailed explanation-3: -(SING-gul-blind STUH-dee) A type of clinical trial in which only the researcher doing the study knows which treatment or intervention the participant is receiving until the trial is over. A single-blind study makes results of the study less likely to be biased.
Detailed explanation-4: -One strategy for disentangling the placebo effect from these non-specific effects is to include a no-treatment-control (NTC) arm in which a group of participants receives neither placebo nor active treatment.
