Values (in mg/L) are means ± standard deviation. Different symbol pairings signify statistically significant values (p < 0.05); when comparing transitional and mature milk individual HMO and total, differences in groups are represented by a,b. # is used if the difference between secretor/non-secretor groups is significant.
