Prognostic value of blood urea nitrogen-to-albumin and C-reactive protein-to-albumin ratios in acute stroke compared with established clinical and radiological predictors: a single-center retrospective cohort study
This single-center retrospective study of 736 acute stroke patients found that while the C-reactive protein-to-albumin ratio (CAR) showed a modest independent association with in-hospital mortality, both CAR and the blood urea nitrogen-to-albumin ratio (BAR) demonstrated limited discriminatory performance compared to established clinical and radiological predictors like lesion volume and stroke severity scores.
