The article, “Effect of Dietary Ribonucleotides on Infant Immune Status. Part 1: Humoral Responses,” by Joseph P. Schaller, Matthew J. Kuchan, Debra L. Thomas, Christopher T. Cordle, Timothy R. Winship, Rachael H. Buck, Geraldine E. Baggs, and J. Gary Wheeler (Pediatric Research 56: 883–890), contained several errors.

On page 886, right column, paragraph 1, the sentence beginning “Comparison of the RCFD” should read: Comparison of the RCFD curves revealed statistically significant distribution differences only at 12-mo (FN different from F, p = 0.023) using the Kolmogorov-Smirnov test (30).

On page 887, the third footnote in Table 3 should read: Different by a post hoc three-group RMA on the evaluable data subset for 6, 7, and 12 mo group X time interaction p = 0.0285.

On page 888, for the legend of Figure 1, the sentence beginning “Reverse cumulative distributions” should read: Reverse cumulative distributions were different at 12 mo (¶FN > F, p = 0.023).

On page 889, right column, paragraph 2, the sentence beginning “In this regard,” should read: In this regard, it is most interesting that significant differences in key indicators of immune function (poliovirus VN1 responses and subsets of T and NK cells) were identified not only between formula groups but also more often between breast-fed infants and those fed formula without ribonucleotides.

Table 2 had missing percentage values and is reprinted below.
