Priya Ranganathan et al. Perspect Clin Res. 2015 Oct-Dec.

Abstract

In biomedical research, we are often interested in quantifying the relationship between an exposure and an outcome. "Odds" and "Risk" are the most common terms which are used as measures of association between variables. In this article, which is the fourth in the series of common pitfalls in statistical analysis, we explain the meaning of risk and odds and the difference between the two.

Keywords: Biostatistics; odds ratio; risk.
