Pulmonary function tests, as well as clinical tests of other physiologic functions, have been adopted from the clinical setting for use in epidemiologic studies. Because these tests require an individual's maximal effort, they present a challenge to conventional standards of measurement validity. The author demonstrates that attempts to standardize spirometry in current epidemiologic studies reveal a bias that causes underestimation of adverse pulmonary effects of occupational hazards.
肺功能测试以及其他生理功能的临床测试，已从临床环境中采用，用于流行病学研究。由于这些测试需要个人尽最大努力，它们对传统的测量有效性标准提出了挑战。作者表明，当前流行病学研究中标准化肺活量测定法的尝试揭示了一种偏差，这种偏差导致对职业危害的不良肺部影响估计不足。
