Incorrect Data in: Role of Staphylococcus aureus Nasal Colonization in Atopic Dermatitis in Infants: The Generation R Study

Arch Pediatr Adolesc Med. 2010;164(4):334. doi:10.1001/archpediatrics.2010.27

Incorrect Data: In the Original Article entitled “Role of Staphylococcus aureus Nasal Colonization in Atopic Dermatitis in Infants: The Generation R Study” (2009;163[8]:745-749), incorrect data appear in Table 2 and Table 3, footnotes a and d in Table 2, footnote d in Table 3, and the text. In addition, the text referring to Table 2 and Table 3 on page 746 should read as follows: “At each visit, nasal samples for S aureus isolation were collected: 622 infants had a swab taken at age 1.5 months, 774 at age 6 months, and 706 children at age 14 months. A total of 758 infants/children attended all the visits; 353 provided 3 swabs to use for longitudinal analysis.” The text referring to Table 2 and Table 3 on page 747 should read as follows: “Because we selected 353 of 1079 infants for a part of the analyses, selection bias may have occurred. Selected infants had fewer missing data from the questionnaires.”

“Of the 353 selected participants, 26.0% had AD in the first year of life and 23.3% in the second year. We missed data that pertain to AD symptoms for 6.1% and 4.3%, respectively. Of the remaining participants in the total cohort (n = 636), 22.6% and 26.7% experienced AD in the first and second years of life, respectively, and data were missing for 13.7% and 16.0%, respectively. The eczema history of the mother was similar to the total cohort.” The text referring to Table 2 and Table 3 on page 748 should read as follows: “In our study, 353 was the smallest number of infants with all 3 swabs available. A larger sample was studied for the individual swab results. These 353 infants were selected based on their attendance at the research center and willingness to provide a nasal swab. One can speculate whether these are children with fewer or more physical problems. Either the parents may be more willing to participate when their child is ill or medical care is sought in different ways when the child is too ill to participate, with the implication that study participation in that instance is not wanted by the parents. However, because we do not see great differences in AD prevalence between the selected 353 participants and the total cohort, selection by AD is not likely to have happened.”

The corrected Table 2 and Table 3 appear here.
