Version Notes

Order Reprints

The authors wish to make a correction to Section 2.7 and Table 4 in the published version of their paper [1].

Table 4. Major Human Milk Oligosaccharides HMOs detected in breast milk glycome and provided to preterm infants with “faster” or “slower” growth during the W2 to W4 lactation period.

A reverse digit error was found when reporting the monosaccharide compositions of Human Milk Oligosaccharides (HMOs) in Table 4 and, in particular, in the order of hexose (Hex), N-acetylhexosamine (HexNac), fucose (Fuc), and N-acetylneuraminic acid (NeuAc) numbers in the first 12 HMOs. A corrected version of Table 4 is shown below.

One edit to the sentence in the paragraph of 2.7. Lipidomic, Metabolomic, and Glycomic Data Treatment and Metabolites Annotation is needed: “When it was not possible to clearly determine HMO structures, HMOs were named according to their monosaccharide compositions and denoted as hexose (Hex), fucose Fuc), N-acetylhexosamine (HexNac), and N-acetylneuraminicacid (NeuAc) numbers”. This sentence should now read: “When it was not possible to clearly determine HMOs structures, HMOs were named according to their monosaccharide compositions and denoted as hexose (Hex), N-acetylhexosamine (HexNAc), fucose (Fuc), and N-acetylneuraminic acid (NeuAc) numbers”.

This change does not affect anything in the overall results of the selection of HMO biomarkers of infant early growth.

The authors would like to apologize for any inconvenience caused to readers by these changes.

Relative HMO abundances (%) were calculated by dividing absolute HMO peak area by each sample’s total HMO peak areas. Values are medians (25% and 75% percentiles) from relative HMOs abundances from week 2 to week 4 of lactation period. P-values for comparison between “faster” and “slower” growth groups were derived by using Mann–Whitney U test. Variables were considered significantly modified between the two groups of infants’ growth when their multiple comparisons adjusted p-values (e.g., q-value after False Discovery Rate (FDR)) was <0.05. *: FDR-corrected MW q-value < 0.05; **: FDR-corrected MW q-value < 0.01; ***: FDR-corrected MW q-value < 0.001; t: FDR-corrected MW q-value < 0.1. Multiple Linear Regression (MLR) for infant weight Z-score (p-value) was also combined with FDR and predictive ability for infant weight growth were considered reliable when MLR q-value was <0.05. *: FDR-corrected MLR q-value < 0.05; t: FDR-corrected MLR q-value < 0.1. ≠: variables of importance for Partial Least Square-Discriminant Analysis (PLS-DA) model (VIP > 1.0).

Fucosylation was further investigated to determine difference in abundance of mono, di, tri, and tetrafucosylation (based on the number of fucose residues).
