What does "bias” mean?

Bias are prejudices in favour of or against something, and it makes us wrongly conclude about the effects of a treatment. It is essential to detect any kind of bias in the biomedical research that may induce unsafe or ineficient studies, as well as the suspension of useful treatments.

Researchers try to avoid bias using aleatorization and anonymization (blind), thus obtaining objective assessments in the evaluation of the studies.
