  1. *Odds ratio and confidence intervals are estimated using logistic regression
  2. ** Odds ratio and confidence intervals are estimated using multinomial logistic regression models with generalized estimating equations (GEE); odds ratio interpreted as the odds of exposed being in a higher category compared to unexposed. Respondents were asked to "score each question on a scale of 1 – 11, one representing never and 11 representing always.
  3. Controlled for age, gender, race/ethnicity, education and smoking history
