Red blood cell distribution width to albumin ratio as a predictor of mortality in ICU patients with community acquired bacteremia.
Observational study in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 1 of them a synthesis that pooled it.
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
Bloodstream infections are globally occurring life-threatening diseases that impose significant societal and economic burdens. This study explored the red cell distribution width (RDW) to albumin ratio (RAR), a novel index derived from RDW, to investigate its relationship with prognosis of bacteremia using propensity score matching (PSM). This retrospective observational cohort study included patients with bacteremia admitted to Yantai Yuhuangding Hospital's intensive care units from June 2019 to December 2022. PSM was performed to adjust for confounding factors. The relationship between RAR and mortality was assessed using receiver operating characteristic curves, multivariate, and Kaplan-Meier analyses. A total of 411 patients were included. The RAR threshold of 5.824% /g/dL was determined by maximizing the Youden index; the study population was divided into two groups based on this cutoff value. After PSM, 125 pairs of score-matched patients were generated. Using logistic regression analysis, patients with RAR ≥ 5.824% /g/dL exhibited significantly higher mortality than did those with RAR ＜ 5.824% /g/dL in the entire cohort (OR = 3.926, 95% confidence interval (CI): 2.408-6.400, p < 0.001) and the PSM subset (OR = 2.460, 95% CI: 1.411-4.289, p = 0.040). RAR results were consistent when treated as continuous or four-categorical variables (based on quartiles). Similar outcomes were found for 28- and 90-day mortality and septic shock. The areas under the curves of RAR were 0.735, significantly higher than those of albumin or RAR alone. RAR emerges as an independent risk factor for mortality and septic shock in critically ill patients with community-acquired bacteremia, whether considered a continuous or categorized variable, irrespective of PSM adjustment.
