Table summary
This table displays the results of Questionnaire and biomonitoring estimates for nonsmokers aged 6 to 79 reporting regular exposure to secondhand smoke by reported location of exposure and sociodemographic variable. The information is grouped by Category and sub-categories (appearing as row headers), Self-reported secondhand smoke exposure locations, Number, At home and outside, Reported %, Detectable cotinine % and C_COT-GM (μg/g) (appearing as column headers).

High education category = with a post-secondary graduation. C_COT-GM = creatinine-adjusted cotinine geometric mean (not calculated for exposure outside home). Significant differences (p < 0.05) are indicated by (a) between dichotomized categories, by (b) if different from low income and by (c) when different from middle income. CI = confidence interval.
