Abstract: BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR) signifies systemic inflammation, which may correlate with worse outcomes in intracerebral hemorrhage (ICH) patients. This study explored NLR as a prognostic marker of functional outcomes in ICH and compared it with the ICH score. METHODS: This cross-sectional study was conducted at a tertiary-care hospital in India. Blood was collected from patients with ICH to calculate NLR. Functional outcomes were evaluated using the modified Rankin Scale (mRS) at discharge and 90 days follow-up. RESULTS: The area under receiver operating characteristic curve (AUROC) for NLR predicting poor mRS scores (3-6) at discharge was 0.695 (p = 0.109), and at follow-up, it was 0.729 (p < 0.001) with a cut-off of ≥7.2, sensitivity 68%, and specificity 72%. The AUROC for ICH score was 0.846 (p = 0.003) at discharge and 0.845 (p < 0.001) at follow-up. DeLong's test indicated the ICH score had significantly better predictive performance than NLR at follow-up (p = 0.018). CONCLUSIONS: NLR is a potential prognostic marker for ICH outcomes, showing significant predictive value at 90 days follow-up. However, the ICH score remains a more reliable predictor. Integrating NLR into the ICH score may enhance its prognostic accuracy, but further validation in multicentric studies is needed.
