The abundance of Bacteroides_vulgatus across gut microbiome samples:
For taxonomic groups (e.g. species), abundance is defined as the proportion of cells that are from a taxonomic group
For functional groups (e.g. gene families), abundance is defined as the average copy-number of the function per cell
the abundance of Bacteroides_vulgatus was estimated across human gut metagenomes
Samples with an abundance of zero were assigned the smallest non-zero value
the average abundance of Bacteroides_vulgatus was compared to the average abundance
of other groups at the same functional or taxonomic level
The prevalence of Bacteroides_vulgatus across gut microbiome samples:
is defined at the percent of samples where Bacteroides_vulgatus is found
the prevalence of Bacteroides_vulgatus was estimated across human gut metagenomes at different abundance thresholds
the prevalence of Bacteroides_vulgatus at a minimum abundance of 0.001 was compared to the prevalence
of other groups at the same functional or taxonomic level.
Association of Bacteroides_vulgatus abundance with clinical phenotypes:
Wilcoxon rank-sum tests
were performed to determine if the abundance of Bacteroides_vulgatus was different between cases and controls for several diseases (see table)
For each disease, case and control individuals were selected from the same country and individuals with co-morbities were excluded
See the documentation for more information on these cohorts
p_value indicates whether there is a significant difference in the abundance of Bacteroides_vulgatus between cases and controls
rank and percentile indicate how the p_value for Bacteroides_vulgatus compares to other functional or taxonomic groups
For example, a percentile of 5.0 indicates your p_value was more significant than 95% of other functions or taxa
