Cohort study reveals nonlinear association between blood urea nitrogen and ICU mortality in sepsis, suggesting risk stratification potential.
A nonlinear association was observed between the BUN/Albumin ratio and 28-day ICU mortality among patients with sepsis, with an inflection point established at 20.91 mg/g. This readily accessible parameter has the potential to aid in early risk stratification within the ICU setting. Additional research is warranted to validate these findings.
