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
purposeThis study aimed to evaluate the prognostic value of the red cell distribution width (RDW) to albumin (RA) ratio in predicting in-hospital, three-month, and one-year mortality in elderly patients undergoing hemiarthroplasty for hip fractures.
methodsThis retrospective, single-center, observational study included patients aged 65 years and older who underwent hemiarthroplasty for a hip fracture between January 2018 and December 2023. Demographic data, laboratory parameters, and mortality outcomes (in-hospital, three-month, one-year) were analyzed. Logistic regression models were used to identify independent risk factors for mortality, and receiver operating characteristic curve analysis was performed to assess the predictive value of the RA ratio compared to RDW alone.
resultsA total of 532 patients were included. Of the patients, 212 (39.8%) died within one year. The RA ratio was significantly higher in non-survivors (p < 0.001). Multivariate logistic regression showed that the RA ratio was an independent risk factor for in-hospital (OR: 1.45, 95% CI: 1.13-1.87, p = 0.004), three-month (OR: 1.66, 95% CI: 1.34-2.06, p < 0.001), and one-year mortality (OR: 2.09, 95% CI: 1.66-2.63, p < 0.001). The AUC for RA was higher than RDW alone for in-hospital mortality (0.76 vs. 0.66, p = 0.004), three-month mortality (0.66 vs. 0.59, p = 0.007), and one-year mortality (0.68 vs. 0.61, p = 0.002).
conclusionThe RA ratio is a significant predictor and independent risk factor for short- and long-term mortality in elderly hip fracture patients undergoing hemiarthroplasty. Given its superior prognostic value compared to RDW alone, the RA ratio may serve as a useful, readily available biomarker for early risk stratification in clinical practice.
