CORRECTION
When the article “Prenatal Primary Prevention of Mental Illness by Micronutrient Supplements in Pregnancy,” by Robert Freedman et al. (doi:10.1176/appi.ajp.2018.17070836) was published online on March 21, 2018, some clarifying information on dose and timing was not included in footnote “a” of Table 3. The footnote was updated for the article’s appearance in the July 2018 issue.
