Association between red blood cell distribution width to albumin ratio and prognosis in patients with sepsis-associated acute kidney injury: a retrospective cohort study

Key Points

• Elevated red blood cell distribution width to albumin ratio is linked to increased early mortality.
• 28-day mortality is higher in patients with elevated RAR levels, indicating poor prognosis.
• This observational analysis shows that combining RAR with albumin improves mortality prediction.
• Results highlight the need for further validation of RAR as a prognostic marker for acute kidney injury.
