Two errors appeared in Table 1 (“Characteristics of the entire subcohort, total pregnancy sample, and normal pregnancy samples”) of a research article published in the online March 2011 issue of the Journal (Mijal RS, Holzman CB, Rana S, Karumanchi SA, Wang J, Sikorskii A.

Under the 2 columns of the table labeled “Total pregnancies, sample (n = 1302),” the percentage of white women (Characteristic: Maternal/Race/White) under the column labeled “Weighted (%)” (column 5) should have read 65.7% rather than 66.7%.

Under the 2 columns of the table labeled “Normal pregnancies, sample (n = 668),” the percentage of smokers who smoked less than half a pack per day (Characteristic: Maternal/Smoking/<One-half pack/d) (column 7) should have read 9.8% rather than 9.6%.
