1All odds ratios are for persons living for a given number of years within the buffer of specified extension around a specified type of site, adjusted for: age, gender, race (Caucasian non-Hispanic: yes versus no), current smoker status (yes/no), years smoked, average cigarettes/day if and when smoking, and education (less than high school, high school, post-high school).
