ets exposure, lung cancer - Legacy Tobacco Documents Library

Kabat, G .C ., and Wynder, E .L ., "Lung Cancer in Nonsmokers," Cancer
53(5) : 1214-1221, 1984 .
In 1984, Kabat and Wynder published results of a case-
control study of hospitalized individuals, mostly from New York
City . A total of 25 male cases and 53 female cases and their -
matched controls were included . The authors wrote :
The plausibility of a role of passive
inhalation in lung cancer can be questioned on
several grounds . . .
Cases do not differ from controls except for
the greater exposure to cigarette smoke at
work reported by male cases compared to male
controls .
The authors reported that 18 of 25 male cases versus 11
of 25 controls reported being exposed to ETS in the workplace .
This result was statistically significant at P = 0 .05 . The point
estimate for workplace exposure of males was reported elsewhere as
3 .27 (95o CI 1 .01-10 .6) . However, the authors' reported results
for women are inconsistent with their conclusions on men ; 26 of 53
female cases versus 31 of 53 controls (i .e ., fewer cases than
controls) reported exposure in the workplace . This result, a point
estimate of 0 .68 (95% CI 0 .32-1 .47), is not statistically
significant .
