Study design

Animal study

Research performed in animals rather than humans.

Definition

Animal study: Animal studies can reveal mechanisms and early safety signals. They cannot by themselves prove human benefit or human risk.

What it can tell you

It can show how close the evidence is to a real human health outcome.

What it cannot tell you

It cannot prove that a treatment works in people unless human outcome data are available.
