吸烟和肺癌无正相关

据君豪北京回收软中华烟网了解:1947年,英国的多尔(生物统计学家)和研讨者希尔,在伦敦及周边选了20家医院的肺癌患者做病例组,一起组织了其他的患者来对照;每家医院都有一个社工和患者做访谈查询。访谈以广撒网的方法规划疑问,包含离煤气厂的远近,吃炸鸡的次数,晚餐爱不爱吃腊肠等疑问,虽然多尔不相信肺癌与吸烟有关,但他在疑问中隐藏了对吸烟习气的查询。到1948年5月,收到了156份访谈成果,经重复挑选,发现与肺癌有切当相关的缘由,只要一个!即是吸烟。今后连续收到更多的访谈陈述,进一步加强了这种联络。吸烟的多尔,在得到数据后决然地把烟戒掉。随后以“吸烟与肺癌”的论文宣布在当年9月的《英国医学杂志》上。

美国的医学生温德尔,在闻名的肺外科医生格雷厄姆的支持下,也进行了相似的访谈研讨,研讨者问询肺癌患者和对照的其他患者的吸烟史,计量两组中吸烟者与非吸烟者的份额,评价吸烟者是不是得肺癌的多,并与对照组对比,用这种得出了吸烟致使肺癌的想象。文章稍早于多尔的论文宣布在《美国医学协会杂志》(JMMA)上。相同的,感受到肺癌的要挟,格雷厄姆当即戒掉吸了50年的卷烟(意外的是格雷厄姆在戒烟5年后,没逃脱肺癌的丧命冲击)。
