Abbreviations: CI, confidence interval; OR, odds ratio; OTU, operational taxonomic unit.

OR (95% CI) per increment unit increase. Values in bold represent statistically significant values. ORs are adjusted for treatment strategy group assignment. No other covariates tested were considered a confounder.

Coefficient multiplier. ORs reflect the change in odds per increment unit increase in predictor variables.
