The following variables were included to control for the effects of smoking: smoking status; average number of cigarettes; squared average number of cigarettes; number of years smoking (time-dependent); number of years since quitting (time-dependent); and interactions between ethnicity and smoking status, average number of cigarettes, squared average number of cigarettes, and number of years smoking.
