Errors in Data Input in Results, Figure, and Table

There were pervasive errors in the Original Investigation titled “Association Between Initial Use of e-Cigarettes and Subsequent Cigarette Smoking Among Adolescents and Young Adults: A Systematic Review and Meta-analysis,”¹ published online on June 26, 2017, and in the August issue of JAMA Pediatrics.

The errors in data input affected unadjusted odds ratios and adjusted odds ratios in the Results section of the Abstract and main article, as well as in Figure 2 and Table 2.² The conclusions and interpretations of the article were not affected by these errors or the corrections. In addition, the authors updated the Supplement with a new eTable that identifies sources of specific input data. This article was corrected online.
