There are incorrect statements in “Trends in Spontaneous and Indicated Preterm Delivery Among Singleton Gestations in the United States, 2005–2012”1 by C. Gyamfi-Bannerman and C.V. Ananth (Obstet Gynecol 2014;124:1069–74). In the Materials and Methods section on page 1070, there is a sentence that incorrectly states that the 2003 birth certificate data had been uniformly instituted across all states in 2012. In the same sentence, there are incorrect numbers indicating the number of states using the revised birth certificate. The correct sentence is: “The revised birth certificate was used by 12 states in 2005 (Florida, Idaho, Kansas, Kentucky, Nebraska, New Hampshire, New York [excluding New York City], Pennsylvania, South Carolina, Tennessee, Texas, and Washington), 19 states in 2006 (adding California, Delaware, North Dakota, South Dakota, Ohio, Vermont, and Wyoming), 22 states in 2007 (adding Colorado, Indiana, and Iowa), 27 states in 2008 (adding Georgia, Michigan, Montana, New Mexico, and Oregon as well as New York City), 28 states in 2009 (adding Utah), 33 states in 2010 (adding Illinois, Maryland, Missouri, Nevada, and Oklahoma as well as the District of Columbia), 36 states in 2011 (adding Louisiana, North Carolina, and Wisconsin), and 38 states in 2012 (adding Massachusetts and Minnesota).” The authors regret these errors.
