MSE = Movie Smoking Exposure. Coefficients for Black Teen and Not-Black Teen represent intercepts for each group.

^aDichotomous variable; reference group as indicated.

^bModeled as a continuous variable; trimmed at approximately the 5^th and 95^th percentile values to avoid possible distortion due to outliers and estimates are scaled to reflect the difference in initiation associated with moving from the 5^th to the 95^th percentile.

^cOrdered categorical variable; estimates are scaled to contrast the lowest level with the highest.

Significant p values are bolded. Analysis excludes 519 participants lost to follow up and 35 participants with missing data on covariates.
