Relative to patients in non-UTI group after ICH, those in UTI group presented higher proportions of age ≥65y (p = 0.002), higher NLR (p = 0.018), higher TNF-α (p = 0.011), higher G (p = 0.002), as well as higher D-Dimer (p < 0.001). This evidence concerns the gene TNF and bacterial urinary tract infection.
