2. Figure 1
Summary of secondhand smoke exposures in those with and without atrial fibrillation. Values are reported as percentages for yes/no questions and medians for numeric responses. Y error bars denote interquartile ranges. Questions are limited to a priori selected criteria (see text).

3. Figure 2
Odds ratios for atrial fibrillation by secondhand smoke exposure. The odds ratios for atrial fibrillation (black square) are shown after adjusting for age, sex, race, smoking status, years of smoking, alcohol consumption, diabetes, hypertension, coronary artery disease, and congestive heart failure. Y error bars denote 95% confidence intervals.

4. Figure 3
Odds ratios for atrial fibrillation stratified by the presence of cardiovascular risk factors. Shown are the adjusted odds ratios for the associations between secondhand smoke and atrial fibrillation, stratified by the presence (gray square) or absence (white square) of at least 1 of the following risk factors: age >60, diabetes mellitus (DM), hypertension (HTN), coronary artery disease (CAD), or congestive heart failure (CHF). Odds ratios are adjusted for age, sex, race, smoking status, years of smoking, alcohol consumption, DM, HTN, CAD, and CHF. Y error bars denote 95% confidence intervals.
