To the Editor I write on behalf of my coauthors to report errors in our article, “Association Between Initial Use of e-Cigarettes and Subsequent Cigarette Smoking Among Adolescents and Young Adults: A Systematic Review and Meta-analysis,” that was published online on June 26, 2017, and in the August issue of JAMA Pediatrics.1
First, we had inadvertently input incorrect transition probabilities of cigarette smoking initiation by e-cigarette use status and, as a result, the wrong unadjusted odds ratio of this initiation from the study by Leventhal et al.2 After using the correct data, the correct pooled transition probabilities for cigarette smoking initiation equaled 23.2% for ever e-cigarette users and 7.2% for never e-cigarette users across all studies (not the originally reported 30.4% for ever e-cigarette users and 7.9% for never e-cigarette users). In addition, the correct pooled unadjusted odds ratio of cigarette smoking initiation by ever e-cigarette use equaled 3.83 (95% CI, 3.74-3.91) across all studies (not the originally reported 5.12 [95% CI, 4.41-5.95]).
