Table 6 Total self-reported hours of ETS exposure per day related to deaths from lung cancer and coronary heart disease among all never smokers in CPS II cohort with data on self-reported ETS exposure as of 1982. Relative risk (RR with 95% CI) comparing persons with each level of exposure to those without exposure. Proportional hazards linear model (PHREG) is used and adjusted for age at entry.
