Fig 1. Box plot of total BS concentrations.

Fig 1

The median is marked by the horizontal line in the central box. The boxes are limited by the 25th and 75th percentiles. The whiskers (┴) represent the lowest and highest total BS within 1.5 interquartile distance below or above the box. Outliers (○) represent BS concentrations between 1.5 and 3 interquartile distances below or above the box. Extremes (▲) represent BS concentrations more than 3 interquartile distances above the box. Feces was collected at three different points in time; within three days after birth (T1), five to six days prior to NEC (T2), zero to two days prior to NEC (T3). Total BS concentration: sum of all individual BS concentrations, irrespective of the conjugation status, detected with gas chromatography and expressed in μmol/g dry weight feces.*: p < 0.05, **: p < 0.1 (T3: p = 0.07).
