Notes. GRP = gross ratings points; OR = odds ratio; SFA = smoke-free air index.

^aCovariates not shown in this table are age, age-squared, time, race, education, gender, marital status, employment and work area, and region.

^bORs are estimated for 10 recency-weighted exposures for 4 months before the date of Tobacco Use Supplements of the Current Population Surveys.

^cORs estimated for 10 unweighted exposures for 12 months before the date of Tobacco Use Supplements of the Current Population Surveys.

^dParameter estimates are from the negative binomial regression model for 10 recency-weighted exposures for 4 months before the survey.
