Table 2 shows that blood glucose levels, blood leukocyte count, blood C‐reactive protein (CRP) levels, abnormal cisterns, midline shift > 5 mm, intraventricular hemorrhage, intracerebral hemorrhage, subdural hematoma, epidural hematoma, and subdural hematoma were markedly correlated with serum NOX2 levels (all P < 0.05). This evidence concerns the gene CYBB and Subdural hemorrhage.
