Figure 4. Differences in the risk of using tobacco by college attendance in propensity score matched samples, among subpopulations of the cohort of youth (<18 years) who aged into early adulthood (18-24 years) between Waves 1 and 3 of the PATH Study, United States, 2013-14, 2015-16.

Figure 4.

Notes: RD = Risk Difference; Each dot in the figure indicates the difference in risk of using cigarettes between college attenders and nonattenders and line segments indicate 95% CIs for those risk difference estimates. Negative values indicate lower risk among college attenders vs. nonattenders while values at 0 indicate no difference. Each risk difference was estimated in a separate subsample corresponding with subpopulation specified in the row. Nearest-neighbor matching was used within this subsample to balance the covariates. All matched samples were balanced with a 1:1 matching ratio and a caliper of 0.1
