It is acknowledged that this chapter does not cover the critical
appraisal of all types of research articles published in the dental liter-
ature. For further guidance on how to appraise systematic reviews,
clinical guidelines, qualitative research, economic evaluations in
addition to the study designs already discussed, the following key
resources are recommended:
• Critical Appraisal Skills Programme (CASP)
http://www.phru.nhs.uk/~casp/casp.htm and the CASP Inter-
national Network (a collaboration of individuals and organisations
across the world who are interested in helping people develop
skills in making sense of scientific evidence – available in Chinese)
http://www.caspinternational.org.uk/
• The How to read a paper series by Trisha Greenhalgh, available online
via the British Medical Journal website (http://www.bmj.com). The
series is also available as a book:

Medicine. London, BMJ Publishing Group, 1997.
