Errors in Results in Abstract and Text and in Figure 2

In the Original Investigation titled “Association of OPRM1 Functional Coding Variant With Opioid Use Disorder: A Genome-Wide Association Study,”¹ published online June 3, 2020, the genetic correlation between opioid use disorder and PGC (Psychiatric Genomics Consortium) alcohol dependence in Figure 2 should be 0.7335 (SE = 0.1425), not 0.4325 (SE = 0.084), and this trait should be moved to the top of the plot. Also, many of the mean values cited in the Results of the abstract and text are actually just specific estimates (with standard errors) from different analyses and have been corrected. This article was corrected online.
