ARRIVE 2.0 animal research reporting: a guide to the official guidelines

Core reporting items, planned versus performed research, and official sources.

ARRIVE 2.0 supports transparent reporting of animal research. This overview links to the official requirements, explanations and examples below.

Ten core reporting items

1. Study design

2. Sample size

3. Inclusion and exclusion criteria

4. Randomisation

5. Blinding

6. Outcome measures

7. Statistical methods

8. Experimental animals

9. Experimental procedures

10. Results

Additional context

Also report ethics, housing and welfare. Keep planned protocols distinct from performed experiments. A planned sample size is not an observed result, and a model listing is not certification of compliance.
