Most important discriminating species (left) and markers (right) identified by RF for disease discrimination in the (a) cirrhosis and (b) colorectal cancer cross-validation studies. In the left panels, for each species reported on the vertical axis, the top bar (in blue) corresponds to the feature relative importance (with standard deviation reported with error bars) and the two bottom bars refer to the average relative abundance for healthy (in green) and diseased (in red) samples. In the right panels, for each marker the top bar is coloured according to the corresponding species and the two bottom bars refer to the average marker presence.
