Erratum to: “Low-Dose Augmentation With Buprenorphine for Treatment-Resistant Depression: A Multisite Randomized Controlled Trial With Multimodal Assessment of Target Engagement,” by Lee et al. (Biol Psychiatry Glob Open Sci 2022; 2:127–135); https://doi.org/10.1016/j.bpsgos.2021.09.003.
The authors have realized that the enrollment dates for the trial are incorrect. Currently, the Methods section states that participants were recruited from July 2009 to July 2014, but recruitment actually occurred from November 2014 to April 2018.
