Atcheson et al1 attempted to evaluate the association between work-related carpal tunnel syndrome (CTS) and (1) predisposing medical conditions (diabetes mellitus, hypothyroidism, various arthropathies, unclassified inflammatory disorders, and others) and (2) occupational group. There are serious methodological flaws that limit the conclusions that may be drawn from these data: detection bias, inappropriate choice of a comparison group, and misclassification of exposure to occupational ergonomic risk factors. In addition to the methodological problems, we question the authors' interpretation of the reported results.
