Correspondent CSF and blood WBC concentrations in patients with pneumococcal meningitis. Correlation between CSF and blood WBC: all patients (n = 127, rho = 0.234, P = 0.008), patients with a positive blood culture (n = 89, rho = 0.272, P = 0.01) and patients with a negative blood (n = 38, rho = 0.159, P = 0.34). No significant difference in CSF WBC between patients with a positive or a negative blood culture (P > 0.05).
