作者对在1946～1985年期间10491名英国铸钢工人的死亡率进行了队列研究。调查对象全为男性,工龄至少一年,均选自1946～1965年期间在英国十大铸造厂工作的工人.结果表明,铸钢工人胃癌、肺癌死亡率明显高于英格兰、戚尔士居民相应的肿瘤死亡率。胃癌的期望数(E)=77.4,观察数(O)=106,标化死亡比(SMR)=137;而肺癌之E=229.2,O=441,SMR=147.但脑瘤却显著减低:E=19.4,O=10,SMR=51.本调查还采用回归模 The authors conducted a cohort study of the mortality of 10,491 British steelmakers from 1946 to 1985. The survey respondents were all men and worked at least one year, all of whom were workers at the top ten foundries in the United Kingdom from 1946 to 1965. The results showed that the mortality rates of gastric cancer and lung cancer were significantly higher in cast steel workers than in England Tumor mortality. The expected number of gastric cancers (E) was 77.4, the number of observations (O) = 106, the standardized mortality ratio (SMR) = 137 and the lung cancer E = 229.2, O = 441, SMR = 147. However, E = 19.4, O = 10, SMR = 51. The survey also used regression models
