Fig. 2

Differentially abundant taxa between matched normal and colorectal cancer microbiomes. Boxplots with corresponding paired dotplots indicating the relative abundances of several taxa showing differential abundance between tumor and normal samples. Lines connect the abundance in the normal (left) and tumor sample (right). Line colors indicate the directionality of the abundance change (blue and red for decreased and increased abundance in the tumor relative to the normal, respectively). Below we plot the difference between the tumor and normal abundance as grey dots, with the purple line representing the 95 % confidence (95 % CI) interval and the mean. Values at 0 (grey dotted lines) represent no change between normal and tumor
