Figure 2. Repartition of Gestational Age and Microbiota Cluster in 18 Neonatal Intensives Care Units (NICUs) Enrolling More Than 10 Preterm Newborns.

Figure 2.

Among 577 preterm newborns enrolled in the EPIFLORE study, 544 were hospitalized from 18 NICUs enrolling more than 10 preterm newborns each. Difference in gut microbiota composition among NICUs is not only dependent of gestational age (A). As an example, more than 60% of newborns hospitalized in NICU C belonged to clusters 4, 5, or 6 (B) and were considered immature, although more than 60% of them had a gestational age of more than 26 weeks. Conversely, less than 20% of the newborns of NICUs K stratified into clusters 4, 5, or 6, while 50% of them have a gestational age less than 27 weeks.
