Studies on Smoking in Relation to Lung Cancer

Our plain-English summary of Studies on Smoking in Relation to Lung Cancer, by E.C. Hammond.

The study

• Author: E.C. Hammond
• Published: n.d.
• Our copy: from Johns-Manville's own medical library. The article is still under copyright, so we describe it here rather than post it.

In plain English

This scanned copy of E.C. Hammond's article on smoking and lung cancer is badly damaged, so only a limited summary is possible. The scan opens with a notice that the original is illegible or of poor legibility. Much of the text is unreadable, and none of the study's own figures can be reliably recovered or linked to a group. One passage of the author's own text states that, in number of deaths, coronary artery disease was the most important cause of death among the excess deaths discussed in relation to cigarette smoking. A printed discussion by other speakers follows, including Dr. Ernest Wynder and Dr. W. C. Hueper (names garbled in the scan). Wynder described Hammond's study as questioning a large group of healthy men about their smoking and following them to see how often lung cancer occurred in different groups. The speakers' own studies and opinions are not reported here as Hammond's findings. No mention of asbestos was found in the legible text. A clean copy would be needed for the numbers and a complete account.

We wrote this plain-English summary from the full article with the help of AI, and a second AI model checked each sentence against the article. It is not the authors' wording; the abstract and the article are their own account.

What the study did and found

• Design: Prospective study: men were questioned about their smoking habits and then followed. This is as described by a discussant, Wynder.
• Who was studied: A large group of healthy men, as described by Wynder in the discussion. Numbers, place and dates cannot be recovered from the scan.
• Exposure: Smoking habits, especially cigarette smoking. No dose figures can be recovered.
• Main results:
  • In terms of number of deaths, coronary artery disease was the most important cause of death involved among the excess deaths the author discussed in relation to cigarette smoking. The passage is OCR-damaged, and no figures can be recovered.
