CXCL10 and bacterial infectious disease: Similarly, the median (IQR) urinary levels of IP-10 (pg/mL)/creatinine (mg/dL) were significantly higher in children with UTI [n = 32, 8.3 (18.1)] compared to children without bacterial infection [n = 22, 0.3 (1.0), p < 0.001], also across both age groups, infants <3 months [n = 11, 16.4 (28.7) vs. n = 6, 0.9 (1.4); p = 0.05], and children aged 3 months or older [n = 21, 6.0 (11.8) vs. n = 16, 0.3 (0.7); p < 0.001].
