Combined effects of underground mining (nonuranium mines) and smoking were analyzed in a case-control study of male lung cancer in northern Sweden. Lung cancer cases exposed to underground mining had a considerably lower average cumulative tobacco consumption than other lung cancer cases, indicating that smoking is especially dangerous for underground miners. When relative risks were estimated, a synergistic effect of multiplicative type was found between smoking and underground mining.
在瑞典北部一项针对男性肺癌的病例对照研究中，分析了地下采矿（非铀矿）与吸烟的联合影响。与其他肺癌病例相比，接触地下采矿的肺癌病例平均累积烟草消费量要低得多，这表明吸烟对地下矿工尤其危险。在估计相对风险时，发现吸烟与地下采矿之间存在相乘类型的协同效应。
