CORRECTION
When the article “The Risk of Treatment-Emergent Mania With Methylphenidate in Bipolar Disorder” by Alexander Viktorin et al. (doi:10.1176/appi.ajp.2016.16040467) was originally posted online on Oct. 3, 2016, the hazard ratio reported in the Results section for mania during months 0-3 in patients receiving methylphenidate monotherapy should have been 6.7. The hazard ratio was corrected and the article reposted on Oct. 17, 2016. The article will appear as intended in its print publication in an upcoming issue as well as in its online posting as part of that issue.
