This page provides a statistical comparison of paired data (e.g. by paired t-test or paired rank test). For example, paired-analysis can be used to examine microbial compositino before and after treatment or to study microbial communities sampled from different locations of the same person (e.g. right hand vs. left hand). More details for paired statistical tests can be found here: [Handbook of Biological Statistics].

Choose time points or locations that should be compared by setting the Secondary Group option. Make sure to select different values for G1 and G2. Only those individuals are included for which samples at both time points are available.


Scatter plot of community diversity. Each dot represents the diversity of one individual at two selected secondary groups (G1 versus G2).


Scatter plot of OTU/taxa abundance. Each dot represents the abundance of the selected OTU/taxa of one individual at two selected secondary groups (G1 versus G2). Taxa/OTUs can be selected via the "Taxa" drop-down menu.


Differences in OTU/taxa abundances are shown as bubble plot.


P-values and false discovery rate for paired statistical analysis (paired t-test or paired Wilcoxon rank test).


Option Description
G1 and G2 The two secondary groups to be compared in the paired analysis.
Test Statistical test used for the paired analysis, e.g. paired t-test or paired Wilcoxon rank test.
Sample IDs Show sample IDs in scatter plots.
Taxa A scatter plot is drawn for the selected taxon/OTU.
