Flowchart of patients. 141 patients with community-acquired bacterial meningitis were identified during the study period. After exclusion of 33 patients 108 patients remained for further analysis. Patients were dichotomized according to increased cerebral blood flow velocity (N = 30) and normal cerebral blood flow velocity (N = 78). Abbreviations: CABM community acquired bacterial meningitis, CBFv cerebral blood flow velocity, GOS Glasgow outcome scale (range, 5 no or mild deficit, to 1, death), NLR Neutrophil-to-Lymphocyte ratio.
