FIG 2 .

Composition of gut microbiota in SKOT I and SKOT II. Relative abundances of bacterial phyla (small panels) and families (large panels) in the SKOT I cohort (n = 114) at the ages of 9 months (A) and 18 months (B) and in the SKOT II cohort (n = 113) at the ages of 9 months (C) and 18 months (D). Boxes indicate 25th to 75th percentiles, with mean relative abundances marked as lines and whiskers indicating the range (minimum/maximum) multiplied by the interquartile range (25th to 75th percentiles) from the boxes. Bacterial families are ranked by average relative abundances at the age of 9 months. Detailed information can be found in Table S1 in the supplemental material.
