These patients were statistically older (p < 0.001), had higher concentrations of CRP (p < 0.001), IL-6 (p < 0.001), and D-dimer (p < 0.001), and exhibited lower concentrations of hemoglobin (p = 0.006) compared to those without pneumonia (Table 2). The gene discussed is CRP; the disease is susceptibility to pneumonia measurement.
