As shown in Figure 5, the area under the curve (AUC) for the fitting of urinary tract infection in stone patients with the IL-17A was 0.89, the AUC for the abundance of Intestinibacter was 0.66 and the AUC when combining the abundance of Intestinibacter and IL-17A was 0.89. This evidence concerns the gene IL17A and urinary tract infection.
