Detailed explanation-1: -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-2: -A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over. This makes results of the study less likely to be biased.
Detailed explanation-3: -Single-blind usually means that the research participant is not told of the treatment assignment. Double-blind usually means that the research participant, investigator, study coordinator/nurse, study sponsor, and in some cases the data analyst are kept unaware of the treatment assignment.
Detailed explanation-4: -In a single-blind study, patients do not know which study group they are in (for example whether they are taking the experimental drug or a placebo). In a double-blind study, neither the patients nor the researchers/doctors know which study group the patients are in.
Detailed explanation-5: -A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results.
