Urine samples positive for E. coli infections were compared to CTRLs, non-E. coli and All patients

The area under the curve (AUC), the 95% confidence interval (CI), and the p values are reported. The ROC curves were built using Acetate and Trimethylamine, individually, or combining both concentrations
