In a case referent study of about 600 cases of male lung cancer in northern Sweden the risk in professional drivers was specifically studied. Data concerning occupations, time and type of employment, and smoking habits were collected by questionnaires directed to close relatives. On average, professional drivers were heavier smokers and this was the chief cause of a slightly increased crude risk ratio in the study as a whole. Smoking drivers in an upper age group (70 and over) had a high relative risk of lung cancer, whereas in a lower age group (under 70) no significant increase was found. The relative risk in non-smoking drivers in the upper age group was moderately raised with borderline statistical significance. The high relative risk estimated for smoking drivers in the upper age group suggests a synergistic effect between smoking and occupational exposure.
在瑞典北部一项针对约600例男性肺癌病例的病例对照研究中，专门研究了职业司机的患病风险。通过向近亲发放问卷收集了有关职业、工作时间和类型以及吸烟习惯的数据。总体而言，职业司机吸烟量更大，这是整个研究中粗风险比略有增加的主要原因。年龄较大组（70岁及以上）的吸烟司机患肺癌的相对风险较高，而年龄较小组（70岁以下）未发现显著增加。年龄较大组非吸烟司机的相对风险适度升高，具有边缘统计学意义。年龄较大组吸烟司机估计的高相对风险表明吸烟与职业暴露之间存在协同效应。
