在一项为期5年的肺功能研究中，对花岗岩工人失访进行了检查。我们发现，在研究期间，在离开该行业从事其他工作的工人中，一秒用力呼气量（FEV1）值下降的速度比那些继续就业或退休的工人更快。我们研究了目前推荐的肺功能检查重复性标准的应用，通过观察在多个测试会话中未能满足标准（PFT失败）的不同模式。持续性PFT失败的工人FEV1下降速度比没有或只是间歇性失败的受试者更快。在回归分析中，工作终止被认为是更强烈地与一个陡峭的FEV1斜率时，它已经由一个模式的持续性PFT失败之前。
Granite workers lost to follow-up during a 5-yr study of pulmonary function were examined. We found that in workers who had left the industry for other employment, forced expiratory volume in one second (FEV1) values declined at a faster rate than in those who remained employed or retired during the study period. We investigated the application of a currently recommended repeatability criterion for pulmonary function tests by looking at different patterns of failing to satisfy the criterion (PFT-failure) over multiple testing sessions. Workers with persistent PFT-failure were found to have faster rates of FEV1 decline than did subjects with none or only intermittent failures. In a regression analysis, job termination was found to be more strongly associated with a steep FEV1 slope when it had been preceded by a pattern of persistent PFT-failure.
