Table 3 Estimates of effects of youth vaping on youth smoking

From: Youth vaping and smoking and parental vaping: a panel survey

  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
  1. ATE estimates the average effect of vaping among all youth
  2. ATT estimates the average effect of vaping among youth who do vape
  3. 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)
