Recent authors have suggested that cross-sectional studies of adverse outcome of pregnancy are misleading, and that the only valid method of analysis controls for eventual number of pregnancies. The present study shows, by simple examples, that such a method produces results that cannot be interpreted in the way claimed for them.Mesh:
