Typographical Error in Reports of a P Value

In the Original Investigation titled “Improving Adherence to Long-term Opioid Therapy Guidelines to Reduce Opioid Misuse in Primary Care: A Cluster-Randomized Clinical Trial,”¹ published in the September issue of JAMA Internal Medicine, a typographical error resulted in the incorrect reporting of a P value for discontinuation of opioid treatment in intervention vs control groups in 2 article locations, one in Table 3, the other in the text body on the same page. This article has been corrected online.
