September 2010 (vol. 203, no. 3, page 248)

In an article published in the September 2010 issue of the Journal (Combs CA, Garite T, Maurel K, et al. Failure of 17-hydroxyprogesterone to reduce neonatal morbidity or prolong triplet pregnancy: a double-blind, randomized clinical trial. Am J Obstet Gynecol 2010;203:248.e1-9), a data error appeared in Table 2, “Gestational age at delivery” (page 248.e5).

In the third row under the column headings, on the line labeled “Delivery before 35 wk,” the entry under the “Placebo” column should read “21 (84%)” rather than “13 (84%).” The remainder of the line is correct as published.
