On the basis of multivariate logistic regression analysis, age ≤90 days (odds ratio [OR]: 10.67, 95% CI: 2.90–39.20, P < 0.001); higher DNI (OR: 1.25, 95% CI: 1.08–1.44, P = 0.002), and CRP (OR: 1.02, 95% CI: 1.01–1.04, P < 0.001); and presence of VUR (OR: 3.66, 95% CI: 1.33–10.05, P = 0.012) were independent predictors of bacteremic UTI (Table 3). This evidence concerns the gene CRP and bacterial urinary tract infection.
