Table summary
This table displays the results of adjusted relative risk ratios of heart disease. The information is grouped by sex/smoking status (appearing as row headers), model a (adjusted for age), model b (adjusted for age and other covariates‡), model c† (adjusted for age, other covariates‡ and smoking intensity), model d† (adjusted for age, other covariates,‡ smoking intensity and age of smoking initiation), relative risk ratio , 95% confidence interval and relative risk ratio, calculated using from and to units of measure (appearing as column headers).
