More is less: reducing animal use by raising awareness of the principles of efficient study design and analysis.

Good experimental design and the appropriate use of statistical tests form the corner stone of high-quality scientific research. This is especially important when the experiments involve the use of laboratory animals, to ensure that their use is appropriate and that the minimum number of animals will be used that will provide data which are sufficiently statistically-sound to meet the objectives of the study. One way to raise awareness of the importance of efficient study design and analysis is to provide training courses. This paper reports the views of participants at two such training schools, with reference to why they felt that attendance was necessary and how effective they felt the experience had been. The implications of the responses are discussed, and considerations for future training events are noted.
