An historical cohort mortality study of research and development personnel (primarily chemists) actively employed on Dec 31, 1961, with at least 1 year of service with the Allied Corporation was carried out. These employees experienced lower mortality for all causes of death combined and all cancer causes combined than would be expected on the basis of the general US population. The degree of deficit in all causes of death combined was below the healthy worker effect usually associated with occupational mortality studies of production workers. There was one statistically significant excess, that for cancer of the prostate among research laboratory personnel who worked during the period 1945 to 1955, a period during which researchers may have been exposed to insecticides or fluorine derivatives. Substantial deficits were observed for causes of death known to be related to life-style, suggesting that mortality among Allied's salaried employees, including research and development workers, may have been influenced more by these factors than by occupational factors.
对1961年12月31日在职、且已为联合公司服务至少1年的研发人员（主要是化学家）进行了一项历史性队列死亡率研究。这些员工的所有死因合并死亡率以及所有癌症死因合并死亡率均低于根据美国普通人群预期的死亡率。所有死因合并的死亡率不足程度低于通常与生产工人职业死亡率研究相关的健康工人效应。有一个统计学上显著的超额情况，即在1945年至1955年期间工作的研究实验室人员中前列腺癌的超额情况，在此期间研究人员可能接触过杀虫剂或氟衍生物。观察到与生活方式相关的死因存在大幅不足，这表明联合公司受薪员工（包括研发人员）的死亡率可能更多地受到这些因素而非职业因素的影响。
