Appraisal of different types of study
Different types of studies require you to ask different questions to assess the quality of the evidence. For further information and checklists for the appraisal of different types of studies see, CASP, the Critical Appraisal Skills program.
Amanda Burls (Director of CASP) has written an excellent overview of the meaning of Critical Appraisal that provides a good introduction to the terminology used in this section. [1]
The BMJ series entitled How to read a paper by Trisha Greenhalgh provides excellent overview of the importance of methodological quality for various types of studies. [2]
