Description: Linear discriminant analysis (LDA) coupled with effect size measurements identifies Fusobacterium as the most differentially abundant taxon in colon tumor versus normal specimens by 16S rDNA sequencing in 95 individuals. Tumor-enriched taxa are indicated with a positive LDA score (black), and taxa enriched in normal tissue have a negative score (gray).
