This website is a collection (menagerie) of reporting guidelines for research studies that involve animals. Animals are the subjects of research for many reasons, therefore reporting guidelines address a variety of animal purposes. The goal of reporting guidelines is to improve the approach to reporting research studies so that the results can be used more fully. Incomplete reporting makes it difficult to assess the internal and external validity of studies, so reporting guidelines address both concepts. Reporting guidelines are not risk of bias tools or quality appraisal tools. The reporting guidelines here describe how to report randomized controlled trials, observational studies and experiments.

Many disciplines/topics have also developed topic-specific guidelines. Both veterinary and biomedical examples can be found at other guidelines
