过去几十年中,胰腺癌是人类最主要的肿瘤之一。现在,美国每年大致有20,000人死于胰腺癌。在已有的一些寻找病因的研究中,仅发现吸烟始终是一个较弱的危险因素。本文重新评价了吸烟与胰腺癌的关系,并检验了酒精作为一个可能混淆因素的作用。同样也获得了茶和咖啡摄取量的数据,这些因素在这一疾病研究中一直未曾得到应有的研究。本文作者进行了一项病例-对照询问研究。用Mantel和Haenszeel方法测显著性试验,校正对相对危险度的评价和它们的可信限值。应用10岁为 In the past few decades, pancreatic cancer is one of the most important human tumors. Now, roughly 20,000 people die of pancreatic cancer each year in the United States. In the existing studies to find the cause, only smoking was found to be a weaker risk factor. This article reassesses the relationship between smoking and pancreatic cancer and examines the role of alcohol as a possible confounding factor. Data on tea and coffee intake have also been obtained and these factors have not been properly studied in this disease study. The authors conducted a case-control questioning study. Significant tests were performed using the Mantel and Haenszeel methods to correct for relative risk assessments and their confidence limits. Application 10 years old
