ARRIVE Guidelines

Definition: The ARRIVE guidelines (Animal Research: Reporting of In Vivo Experiments) are a checklist-based set of reporting guidelines developed to improve reporting standards, and enhance replicability, within living (i.e. in vivo ) animal research. The second generation ARRIVE guidelines, ARRIVE 2.0, were released in 2020 . In these new guidelines, the clarity has been improved, items have been prioritised and new information has been added with an accompanying “Explanation” and “Elaboration” document to provide a rationale for each item and a recommended set to add context to the study being described.
