Relationship between PREPARE and ARRIVE
The PREPARE guidelines for planning animal experiments are complementary to reporting guidelines such as ARRIVE. They should be used in conjunction, to ensure that important topics have not been omitted. PREPARE includes topics which may not be necessary to report in a scientific paper, but which can seriously affect the scientific quality of an animal study (as well as causing health risks to both humans and animals) if they are not addressed satisfactorily.
This table shows the 15 points in the PREPARE guidelines checklist, with the 20 points in the ARRIVE guidelines for comparison. Note that, unlike ARRIVE, the topics in PREPARE (which are grouped into three main themes) will not necessarily be addressed in order, when planning an experiment.
