Comparison of the relative abundances of phyla/subphyla taxa between the disease unaffected and disease affected regions of resected ileum in ileal CD subjects undergoing initial ICR.

The mean relative abundance ± standard deviation is shown for each bacterial category in Batch 1 (2005–2010) and Batch 2 (2010–2012) as well as the FDR for respectively macroscopic pathology (disease affected vs. disease unaffected) and the sample batch (Batch 1 Batch 2). A total of 101 disease affected and 111 disease unaffected samples were analyzed, of which 91 were paired samples.
