Table 5 Level of spousal smoking related to deaths from lung cancer and coronary heart disease among never smokers in CPS II cohort 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 RR is adjusted for age at entry.
