Epidemiology is integral to medical research. To keep abreast of medical advances related to the specialty, dermatologists need a sound understanding of epidemiologic principles.
Objective:
The purpose of this article is to introduce the case-control study design in the context of dermatology. Topics covered include subject selection, exposure assessment, and data analysis.
Conclusions:
The case-control design is applicable to dermatology research. This method is especially relevant for rare diseases or those with a long latency period.
