Hanley et al. (1) recently provided an excellent explanation of the generalized estimating equations approach to a wider audience. There is no doubt that their article will make this approach even more popular in epidemiologic research. However, the comment on page 374 about the availability of alternative logistic regression in common statistical software is not strictly true. For example, SAS version 8.0 PROC GENMOD can easily be used to fit this model. A clear demonstration can be found on page 1455 of the SAS manual (2).
