Association between trajectory patterns of urea-to-creatinine ratio within 7 days after admission and prognosis in patients with sepsis
Sepsis is a life-threatening syndrome characterized by substantial clinical heterogeneity. The urea-to-creatinine ratio (UCR) is a readily available biomarker reflecting systemic metabolic stress and renal handling; however, the prognostic value of its dynamic trajectories in sepsis remains unclear.
