Another American study was first published in 1991 by<br />

Fontham and colleagues, as a preliminary report on a case-control<br />

study of women in five U .S . cities . For all <strong>lung</strong> <strong>cancer</strong> cell types<br />

combined, an odds ratio of 1 . 34 (95% CI 1 . 03-1 .73) was reported for<br />

those women who reported that they were ever exposed to ETS in an<br />

occupationall setting . Fontham and colleagues (1994) recently<br />

published a report on all five years of the study . They present a<br />

"crude" riskk estimate for workplace <strong>exposure</strong> of 1 .12 (955~ CI 0 .91-<br />

1 .36), which changes dramatically after adjustment for a number of<br />

variables to 1 .39 (95% CI 1 .11-1 .74) . The magnitude of the change<br />

following adjustment is much more pronounced for the workplace risk<br />

estimate than for the other risk estimates in the paper . Moreover,<br />

the upward increase after adjustment_is suspicious . Fontham and<br />

colleagues do not address this apparent discrepancy .<br />
