Fig. 6From: The influence of spaceflight on the astronaut salivary microbiome and the search for a microbiome biomarker for viral reactivationSalivary microbiome can predict viral status. Results from the random forest classifier showing the bacterial genera that are the most discriminatory between viral positive (qPCR detection of EBV or HSC-1) and viral negative samples, in descending order. OOB error rate was 24%, and LOOCV accuracy was 75%. Taxa are colored based on whether they were significantly higher in viral positive samples (red), viral negative samples (blue), or not (black) based on the Wilcoxon rank test with a Benjamini-Hochberg correction for multiple comparisons.
