Two statistics were incorrect in the study results provided in a research paper published in October 2011 (McDonald SD, Pullenayegum E, Taylor VH, et al. Despite 2009 guidelines, few women report being counseled correctly about weight gain during pregnancy. Am J Obstet Gynecol 2011;205:333.e1-6.).

In Table 2, “Patient perception of prenatal counseling recommendations” (page 333.e3), under the heading “Respondents, n (%)” for subjects who “Were counseled to consume an amount or range of additional calories each day by health care provider” (sixth category under Outcome), the correct total is 55 (17.9), not 253 (17.9), as published. (The total is 55 because values were missing for 5 subjects.)

The Results section of the text, beginning with the final paragraph in column 1 on page 333.e4, states: “Fewer than 1 in 5 patients (17.7%) reported that their health care provider recommended that they eat a specific range of additional calories each day; one-third of them could not recall the amount that had been recommended.” The correct percentage is 17.9%.
