  1. Entries were age-adjusted per 100 individuals by level of ETS exposure. * linear trend < 0.05, ** < 0.005, < 0.0001. Odds ratios were adjusted for age, alcohol consumption, body mass index, diabetes, ethnicity, education status, hypertension, marital status, physical activity at work, serum total cholesterol, and individual occupational hazards. Standard deviation (SD) for home exposure = 19.9 hours/week; SD for small spaces exposure = 15.5 hours/week; SD for large indoor areas exposure = 13.4 hours/week; SD for total exposure = 24.7 hours/week.
