Testing the Homogeneity of the Relative Risk Under Multiple Matching
针对多重匹配病例对照设计，提出了一种检验相对风险同质性的新方法，无需对匹配协变量进行显式分层。
A new procedure is developed for testing the homogeneity of the relative risk in a multiply-matched case-control design, both with constant and variable matching. The test does not require explicit stratification on the matching covariate.
