摘要
Matched case-control studies often include pairs with incomplete exposure information. This work presents and compares two estimator, for the odds ratio that can be used when the exposures of some of the cases and controls are missing. A simulation study shows that the estimator that uses the marginal exposure frequencies is usually more efficient than the estimator based on discordant pairs.
