Smoking among cancer patients
Usage
data(Schrek_1950)
Format
Schrek_1950: A data.frame object with one row for each patient.
-
age: The patient's age. This is rounded down to the nearest decade, since Schrek et al. presented
ages as 20, 30, 40, 50, ...
-
site: The site of the patient's tumor: "lung", "lip", "larynx", "other
-
smoker: Whether the patient smoked: "smoker", "nonsmoker". More accurate names for the
levels would be "moderate or heavy smoker" and "nonsmoker or light smoker." Light smoking
was defined as consuming 10 or fewer cigarettes per day (or, two or fewer cigars or three or fewer pipe
bowls).
Details
Schrek_1950 is a reconstruction of the "raw" data behind the
summary presented in Schrek et al. (1950) "Tobacco Smoking as an Etiologic Factor in Disease. I. Cancer"
Cancer Res,10:49-58. That case-control study compared smoking rates among white men with tumors
at different sites. Since the interest was in testing the hypothesis that lung, lip, and/or larynx
cancer is associated with smoking, the control group was those patients with "other" tumors. This choice
of control group was motivated by the availability of subjects and the desire to make the
control group as similar as possible to the case group.
