Title: On a Supplemented Case-Control Design
Author(s): Ruth M. Pfeiffer*+ and Nilanjan Chatterjee and Mitchell H. Gail and Barry I. Graubard
Companies: National Cancer Institute and National Institute of Health and National Cancer Institute and National Cancer Institute
Address: 6120 Executive Blvd./EPS 8030, Rockville, MD, 20852,
Keywords: two-phase design ; pseudo-likelihood ; auxiliary information
Abstract:

The supplemented case-control design consists of a case-control sample and of additional data on a subgroup of disease free subjects that are known to be positive for one of the exposures of interest. This design may help improve precision in the inference of joint exposures in any situation where the prevalence of one of the exposures is low, and additional information from data sources other than the case-control sample is available. We use two-phase design methods to find maximum likelihood estimates for the log odds ratios for this design and apply the method to assess the influence of genetic polymorphisms and radon exposure in lung cancer.
