The researchers are clear that no accepted biological mechanism exists that might explain the epidemiological results and that the relation may be due to chance or confounding. Some correspondents, however, present various hypotheses that might support the idea of a causal connection.1

    Volker Königsbüscher, information technology manager from Switzerland, is not surprised to find the risk extending to such a considerable distance.
