Incorrect Probability Data in a Column in Table 1

In the Special Communication entitled “Extracorporeal Membrane Oxygenation for Severe Acute Respiratory Distress Syndrome and Posterior Probability of Mortality Benefit in a Post Hoc Bayesian Analysis of a Randomized Clinical Trial,” published in the December 4, 2018, issue of JAMA,¹ the prior probabilities of RR <0.7 rather than RR <0.67 (as indicated) were supplied for the various reference priors described in Table 1. The prior probabilities for RR <0.67 for that column are 48%, 50%, 15%, 5%, and 0%. This article was corrected online. This article was also corrected to correct a degree in the author listing and to add a conflict of interest disclosure that was inadvertently omitted.
