Background. There is no evidence suggesting that red blood cell distribution width‐to‐
albumin ratio (RA) predicts outcomes in severely ill older individuals with acute kidney injury
(AKI). We hypothesized that RA is associated with all‐cause mortality in critically ill older
patients with AKI. Methods. We recorded demographics, laboratory tests, comorbidities, vital
signs, and other clinical information from the MIMIC‐III V1. 4 dataset. The primary endpoint
was 90‐day all‐cause mortality, and the secondary endpoints were 30‐day mortality, one …

Background Patients with sepsis with low albumin levels and high red blood cell distribution
width levels have poor prognoses. Red blood cell distribution width to albumin ratio (RAR)
has recently attracted attention as an innovative inflammation biomarker. We aimed to
explore the association between RAR and the prognosis of patients with sepsis. Methods
This retrospective observational study included 402 patients meeting the sepsis-3 standards
admitted to Yantai Yuhuangding Hospital's intensive care units (ICUs) between January …
