This is a basic book on evidence-based medicine (EBM). It starts with an introduction to the topic. It outlines the relationship between EBM and research and quality of care. Then It goes on to cover the most commonly used modules of EBM, i.e. therapy, diagnosis, prognosis and meta-analysis. Each module starts with an introduction to fundamental concepts, and description of the related research process, and then follows the critical appraisal of related type of research artcle. At the end, it covers the different systems of grading of level of evidence and strength of recommendations. The book also has three examples of critical appraisal on diagnosis, therapy, and meta-analysis.
Maybe not a bad text if you know absolutely nothing about these topics, but the coverage is *very* basic and simplistic. I thought this was a weak text. The question/answer format in my opinion doesn't add much; the main thing that is added are superfluous words which take up space that could have been put to better use, e.g. by providing more detailed coverage of key concepts. The language in this publication is in my opinion 'only sort of okay'; occasionally you'll come across poorly constructed sentences, and a few times I was uncertain about the intended meaning of a specific sentence - and in my opinion such sentences should not be found in publications like this one.
