Abstract
The Mantel-Haenszel procedure offers a simple and efficient means of estimating a common rate ratio from incidence density data in cohort studies. A new formula is provided for the variance of its logarithm, comparisons are made with the method of maximum likelihood, and associated tests for heterogeneity and trend in the component rate ratios are described.Mesh:
