The purpose of this study was to determine the factors that are associated with the occurrence of small irregular opacities in the chest radiographs of coalminers, and whether the lung function of miners with irregular opacities differed from that of miners with small rounded opacities, a mixture of small rounded and irregular opacities, or an absence of opacities. A subsample of 6166 coalminers was selected from 9076 miners who had been examined by the US Public Health Service as part of the National Study of Coalworkers' Pneumoconiosis. The subsample consisted of 4479 smokers and 1687 non-smokers. The chest radiograph of each miner was classified according to the UICC/Cincinnati Classification.
本研究的目的是确定与煤矿工人胸部X光片中出现小的不规则阴影相关的因素,以及有不规则阴影的矿工的肺功能是否与有小圆形阴影、小圆形和不规则阴影混合或无阴影的矿工不同。从9076名接受美国公共卫生服务局检查的矿工中选取了6166名作为子样本,这些检查是全国煤矿工人尘肺病研究的一部分。该子样本包括4479名吸烟者和1687名非吸烟者。根据国际抗癌联盟/辛辛那提分类法对每位矿工的胸部X光片进行分类。
