In the Original Investigation titled “Association Between Automotive Assembly Plant Closures and Opioid Overdose Mortality in the United States: A Difference-in-Differences Analysis”¹ published in the February 2020 issue, the fourth sentence of the Results paragraph of the abstract should have read as follows: “Five years after a plant closure, mortality rates had increased by 8.6 opioid overdose deaths per 100 000 individuals (95% CI, 2.6-14.6; P = .006) in exposed counties compared with unexposed counties, an 85% higher increase relative to the mortality rate that would have been expected had exposed counties followed the same outcome trends as unexposed counties.” Also, the y-axis label for Figure 2A should have read “Unadjusted Mortality Rate per 100 000, %.” This article was corrected online.

在原反倾销调查名为“协会汽车装配工厂关闭，并在美国阿片类药物过量死亡率之间：一个差异，在-差异分析” ¹发表在2020年二月号，抽象的结果段第四句应改为如下：“植物关闭五年后，死亡率每10万人中增加了8.6阿片类药物过量死亡（95％CI，2.6-14.6；P = .006），与未暴露的县相比，暴露的县的死亡率相对于未暴露的县要高出85％。此外，图2A的y轴标签应显示为“每10万的未调整死亡率，％”。本文已在线更正。
