The Red Blood Cell Distribution Width to Albumin Ratio Is Associated with in Hospital Mortality and Adverse Outcome in Elderly Chinese Patients with Gastrointestinal Bleeding.
Article in Journal of inflammation research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Gastrointestinal bleeding (GIB) in elderly patients is a common and life-threatening condition, often complicated by comorbidities. The ratio of red blood cell distribution width to albumin (RAR) has recently been proposed as a prognostic marker in various diseases, but its role in predicting adverse outcomes in GIB patients remains unclear. Methods: A total of 51,824 aged 65 years or older patients were initially screened for inclusion in the study. After excluding those lost to follow-up, with missing vital information during the screening period (n = 50,423), 1401 hospitalized patients with GIB in Beijing Hospital (2013-2019) were included. Restricted cubic spline modeling and logistic regression analyses assessed the relationships between RAR, adverse outcomes, and in hospital mortality. Results: Among the 1, 401 patients, 648 experienced adverse outcomes, and 427 patients died during hospitalization. Higher RAR was significantly associated with an increased risk of both in-hospital mortality and adverse outcomes, even after adjusting for age, sex, education level, body mass index (BMI), chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), cancer, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), white blood cell count (WBC), estimated glomerular filtration rate (eGFR), hemoglobin, heart failure, blood urea nitrogen (BUN), and heart rate. Conclusion: RAR is a novel and independent predictor of mortality and adverse outcomes in elderly patients with GIB. Its simplicity and cost-effectiveness make it a valuable tool for identifying high-risk patients. Further studies in larger, multicenter cohorts are needed to confirm these findings and evaluate the clinical benefits of RAR-based interventions.
