How to Read a Paper series

Dr. Trisha Greenhalgh is a British physician and professor of medicine that wrote a series of excellent articles in the mid to late 1990's as the idea of finding, analyzing, and using the best evidence from the literature. Although over 10 years old, her "How to Read a Paper" series of articles, published in the BMJ, still offer valid insight into increasing critical appraisal skills. Note: Some of the articles begin on page two or three of the linked PDF file.
