The ARRIVE guidelines (Animal Research: Reporting In Vivo Experiments) were developed by the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) in 2010. The guidelines are designed to improve the reporting of animal research so that it is more transparent and reproducible. The guidelines cover a range of topics, including the number of animals used, the methods used to reduce pain and distress, and the statistical analysis of the results.
The study found that there was a wide variation in the level of compliance with the ARRIVE guidelines. Some journals required authors to submit a checklist of information about their animal research methods, while others did not. Similarly, some journals required authors to provide a statement of ethical approval, while others did not.
The study also found that there was a lack of consistency in the way that the ARRIVE guidelines were implemented. Some journals required authors to provide more information than others, and some journals had different requirements for different types of animal research.
The study's authors say that the lack of enforcement of the ARRIVE guidelines is a major problem, as it makes it difficult for researchers to assess the quality of animal research studies. They say that journals should do more to enforce the guidelines, and that they should work together to create a consistent approach to reporting animal research.
The study's findings are supported by other research. A study published in the journal Nature in 2018 found that only 50% of animal research studies reported the number of animals used, and only 33% reported the methods used to reduce pain and distress.
The lack of transparency in animal research is a serious concern, as it makes it difficult for researchers to build on the work of others and to identify potential problems with animal research studies. It also makes it difficult for the public to assess the ethical implications of animal research.
The study's authors say that more needs to be done to improve the reporting of animal research. They say that journals should do more to enforce the ARRIVE guidelines, and that researchers should be encouraged to submit their studies to journals that require compliance with the guidelines.
