Impact of the red blood cell distribution width-to-albumin ratio on neurological outcomes in cardiac arrest patients.
Observational study in Frontiers in neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Brain injury remains the leading cause of mortality and morbidity among patients who experience cardiac arrest and cardiopulmonary resuscitation (CA/CPR). There is an urgent need to explore simpler and cheaper biomarkers to predict post-CA neurological outcomes. The red blood cell distribution width-to-albumin ratio (RA) has been used to assess inflammatory responses and prognosis in several diseases. This study was conducted to assess the correlation between RA levels and post-CA neurological outcomes, and to determine the value of RA in predicting neurological function after CA/CPR. Methods: We conducted a retrospective observational study on out-of-hospital cardiac arrest (OHCA) cases presenting to our hospital's emergency department between January 2023 and April 2026. All patients were divided into cohorts with good or poor neurological outcomes according to cerebral performance categories (CPCs). Cox regression models were used to estimate the correlation between RA and neurological outcomes. The area under the receiver operating characteristic curve (AUC) was calculated to evaluate the ability of RA to predict neurological outcomes in patients after CA/CPR. Results: In total, 80 patients were involved, of whom 10 survived to hospital discharge with good neurological function (CPC ≤ 2), while the remaining subjects showed poor neurological function (CPC ≥ 3). RA levels were significantly higher in patients with poor neurological outcomes than in those with good outcomes. The AUC for the RA was 0.90, indicating excellent predictive accuracy. The RA values were independently associated with poor neurological outcomes following CA/CPR, even after adjusting for potential confounding factors. Conclusion: We found that RA is associated with post-CA neurological outcomes, and higher RA levels could serve as a predictor of worse neurological outcomes in patients who undergo CPR after experiencing CA.
