TABLE 3.

Differentially abundant bacterial taxa by CaOx stone status

Organism	Group overrepresented	Indicator value	P value (indicator value)	P value (Wilcoxon rank‐sum tests)
Acinetobacter	Cases	0.69	.005	.007
Geobacillus a	Cases	0.63	.02	.03
Geobacillus a	Cases	0.56	.004	.009
Hydrogenophaga	Cases	0.53	.04	.04
Sphingopyxis	Controls	0.84	.04	.15

Notes: Indicator value represents the product of the mean relative abundance and frequency of a bacterial taxon by experimental group. Permutation tests are performed to calculate statistical significance to determine the P value for the indicator value. Five taxa were identified that had indicator values >.5 and P values <.05 when differentiating case and control groups. The P values for Wilcoxon rank‐sum tests were then calculated between case and control groups for these taxa.

^a Two unique ASVs of the Geobacillus genus were identified as differentially abundant.
