	OR	95% CI	E-Value for OR	E-Value for lower limit
Ever Smoked (n = 3291)
Sample weighted association	29.78	17.89–49.58	59.06	35.27
ATE	12.03	5.16–28.04	23.55	9.79
ATT	10.54	5.99–18.53	20.57	11.46
Current Smoking (n = 3291)
Sample weighted association	37.26	19.78–70.18	74.02	39.05
ATE	22.71	8.99–57.40	44.91	17.47
ATT	10.49	5.04–21.82	20.47	9.55
Smoking Initiation (n = 3075)
Sample weighted association	43.34	15.04–124.89	86.18	29.57
ATE	32.46	9.84–107.09	64.42	19.17
ATT	4.38	0.62–30.94	8.23	1.00

ATE estimates the average effect of vaping among all youth
ATT estimates the average effect of vaping among youth who do vape
The e-value for the OR indicates the minimum strength of association (OR) that an unmeasured confounder would need to have with both youth vaping and youth smoking to reduce this estimate to the null. The e-value for the lower limit indicates the minimum strength of association that an unmeasured confounder would need to have with both youth vaping and youth smoking for the lower limit of the confidence intervals around this estimate to cross the null (all confounders are unmeasured for the sample weighted associations)
