Necessary Clarifications Concerning Results of the SUMMIT Trial

To the Editor In an Original Investigation published in a recent issue of JAMA Internal Medicine, Watkins and colleagues¹ conducted an important trial of collaborative care for primary care patients with probable alcohol and/or opioid use disorders (AUDs and/or OUDs).
