The authors regret “In this paper, we reported on mortality for a cohort of opioid users ascertained by drug treatment or criminal justice sources in England. In Table 1, we reported the number of individuals accrued to the cohort from each setting. However, the original Table 1 contained an error, such that the alignment of settings and their associated counts were incorrect. The correct Table 1 appears below. This error does not alter the analysis or findings of the study.
Table 1.
