This chapter is an accompaniment to the previous chapter (Chapter 4) in which you learnt how to critically appraise evidence about the effects of interventions. In order to further illustrate the key points from Chapter 4, this chapter contains a number of worked examples of questions about the effects of interventions. As we mentioned in the preface of the book, we believe that it can be easier to learn the process of critical appraisal when you see some worked examples of how it is done, and it is even better when the examples are from your own health profession. Therefore, this chapter (and Chapters 7, 9 and 11) contains examples from a range of health professions. Some of the clinical examples are relevant to more than one health profession.
