title: Stratification by a multivariate confounder score.
abstract: The complexity and inefficiency of multiple cross-classification as a means of controlling confounding in etiologic research may be avoided upon summarizing the pattern of confounding factors for each subject in terms of a multivariate score. The control of confounding may be based on stratification by the score, with stratum-specific contingency tables obtained and analyzed in the usual manner.
