Correction of an Author’s Degree and the Map of China in a Figure and eFigure

In the Original Investigation titled “Association of Long-term Exposure to Airborne Particulate Matter of 1 μm or Less With Preterm Birth in China,” published January 2, 2018, and in this issue of JAMA Pediatrics,¹ the degree for author Qin Li has been corrected to “MMSc” instead of “PhD.” As a result of this correction, references to Li in the Author Contributions and Funding/Support sections have also been updated to “Mr Q. Li” instead of “Dr Q. Li.” In addition, Figure 1 and eFigure 2 in the Supplement have been replaced to correct the western border in these maps of China. This article was corrected online.
