In the Original Investigation entitled “Effect of Folic Acid and Zinc Supplementation in Men on Semen Quality and Live Birth Among Couples Undergoing Infertility Treatment: A Randomized Clinical Trial”1 published in the January 7, 2020, issue of JAMA, the data for 2 rows were transposed in Table 1. Under the row labeled “Taking multivitamin within past 3 mo,” the data for “Yes” are 298/751 (40) for the folic acid and zinc group and 284/752 (38) for the placebo group. In the next row, the data for “No” are 453/751 (60) for the folic acid and zinc group and 468/752 (62) for the placebo group. This article was corrected online.
