Measurement of exposure and disease are covered in Chapter 2 and a summary of the different types of study designs and their strengths and limitations is provided in ...
common measures are odds ratios, relative risk, relative risk reduction, absolute risk reduction, and the number needed to treat. The question faced by the practitioner is then: Which one will help me in choosing the best treat-ment for my patient? Methods: The purpose of this paper is to illustrate, using
