Flexible matching in case-control studies of gene-environment interactions.

American journal of epidemiology - 1 Jan 2004

Saunders Catherine L, Barrett Jennifer H

Abstract excerpt

Because of the lack of power of case-control study designs to detect gene-environment interactions, flexible matching has recently been proposed as a method of improving efficiency. In this paper, the authors consider a large-sample approximation method that allows estimation of the most efficient matching strategy when genotype and exposure are either independent or associated. The authors provide tables of the...
