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]).

我代表我的合著者写给编辑，以报告我们在网上发表的文章“电子香烟的初次使用与青少年和年轻人之间随后的吸烟之间的关联：系统评价和荟萃分析”中的错误。 2017年6月26日，以及JAMA Pediatrics的8月号。^1个

首先，我们无意中输入了由电子烟使用状态引起的吸烟引发转变的不正确概率，结果，来自Leventhal等人的研究对这种引发的错误未调整优势比进行了错误的调整。²在使用了正确的数据之后，在所有研究中，正确的合并吸烟开始吸烟的过渡概率对于曾经使用过电子烟的用户为23.2％，从未使用过电子烟的用户为7.2％（并非最初报告的曾经使用过电子烟的用户为30.4％从未使用电子烟的用户占7.9％）。此外，在所有研究中，通过使用过电子烟开始吸烟的正确汇总未调整比值比等于3.83（95％CI，3.74-3.91）（并非最初报道的5.12 [95％CI，4.41-5.95]）。
