Error in Figure 2

In the Original Investigation titled “Association of Hydrocodone Schedule Change With Opioid Prescriptions Following Surgery,”¹ published online first August 22, 2018, in JAMA Surgery, there was an error in Figure 2. The labels should be switched; the upper blue line should be labeled “Other opioid types,” and the lower orange line should be labeled “Hydrocodone.” This article was corrected online.
