Univariate analysis revealed significant differences in the history of diabetes mellitus (p = 0.011), age (p = 0.04), baseline GCS scores (p < 0.001), baseline hematoma volume (p < 0.001), intubation (p < 0.001), levels of CRP (p = 0.034), and Hcy (p < 0.001) for HAP prediction. The gene discussed is CRP; the disease is diabetes mellitus.
