Percentage of infants with high bifidobacteria over time. Based on when each qualifying infant crossed the cutoff point of 108.5 bifidobacterial genome equivalents/gram feces. Infants qualified for this analysis by having the appropriate time points available to know when they are first established with bifidobacteria; for example, if the day 6 sample is missing, it is impossible to know if the infant was established at that time or not, and thus, that infant was excluded from this analysis.
