  1. aClusters were formed using the first 7 principal components (which explained 78% of the total OS variability and had eigenvalues for components > 0.8), considering the 16 mostly represented OS (those in Table 2 plus 2_0_1_0_0; 3_2_0_0_0; 4_0_0_0_0; 4_1_1_0_0. OS values were standardized by Z-score scaling so that, within each OS, mean = 0 and standard deviation = 1. Positive cluster values indicate a local cluster of standardized data values of abundance above the mean, while negative cluster values represent a cluster of standardized data values below the mean
  2. bRefer to the note to Fig. 1 for the simplified nomenclature. FL Fucosyllactose, LNDFH Lacto-N-difucohexaose, LNH Lacto-N-hexaose, LNnH Lacto-N-neohexaose, LNT Lacto-N-tetraose, LNP Lacto-N-pentaose, LNnT Lacto-N-neotetraose, SL Sialyllactose
  3. cContrast: cluster 1 vs. cluster 4 differed for P < 0.05
