Accuracy of predicting disease severity by microbial species. (A) Random forest analysis of the decrease in accuracy (x-axis) of predicting disease severity with the removal of individual species (y-axis). A higher mean decrease accuracy value indicates the importance of that species in predicting severity of disease (moderate vs. critical). (B) Because Candida albicans was the most important species with respect to disease prediction, we further examined this taxon via a Box and Whisker plot to show individual data points.
