I'm not sure that interesting is the right word peer review really refers to the process of publishing research where independent experts in the field review the study methodology and data analysis to ensure that the conclusions are robust. It is, at least a system of sorts but it is flawed in so many ways. That said, the key is in understanding scientific research methodology and being able to judge the validity of the conclusions that the researchers are proposing. That means examining the entire research approach that they have taken and the statistical analysis i.e. were the stats tests appropriate and applied correctly.

It takes a good deal of experience and training to be able to see past the figures quoted in many papers and put them into context of the research methodology which can obviously be difficult for non-scientists/non-medics/vets.

The important thing is to question what is in the literature and identify good quality, well planned and sound research.

Ok chaps...wake up
