CRP and nervous system disorder: On multivariate analysis, platelet count < 100,000/μL (OR, 14.294; 95% CI, 3.358–60.851; p = 0.000), C-reactive protein (CRP) ≥ 5 mg/dL (OR, 3.101; 95% CI, 1.021–9.414; p = 0.046), and the other neurologic disease group were found to be significant factors associated with 30-day mortality (OR, 0.125; 95% CI, 0.016–0.994; p = 0.049) (Table 6).
