Pneumonia patients had significantly higher mean WBC counts (11,334.8 vs. 7515.1 cells/μL, p < 0.001), and CRP levels (98.9 vs. 62.2 mg/L, p = 0.046), but lower mean ALC (1697.9 vs. 2484.7 cells/μL, p = 0.001) compared to non-pneumonia patients. The gene discussed is CRP; the disease is susceptibility to pneumonia measurement.
