Associations between the red blood cell distribution width-to-albumin ratio and 3-month outcomes in patients with acute minor ischemic stroke: A cohort study.
Article in PloS one, 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
Acute minor ischemic stroke (AMIS) patients may experience unfavorable outcomes despite mild initial symptoms. The ratio of red blood cell distribution width (RDW) to albumin (ALB) (RAR) has been associated with poor outcomes after stroke, but its role in AMIS remains unclear. This study aimed to investigate the association between the RAR and 3-month functional prognosis in patients with AMIS. This is a secondary analysis of a single-center, prospective cohort study conducted in Korea that included 988 patients with AMIS with a National Institutes of Health Stroke Scale (NIHSS) score ≤3. The RAR was calculated using RDW and ALB levels measured within 24 hours of admission. The functional outcome at 3 months poststroke was assessed using the modified Rankin Scale (mRS). The associations between the RAR and poor 3-month outcomes (mRS score ≥3) were evaluated using a multivariable logistic regression model, adjusting for confounders and conducting stratified and sensitivity analyses. Multivariate regression analysis revealed that the RAR was significantly associated with poor prognosis, both when it was unadjusted (OR = 2.29, 95% CI: 1.74-3.02, P < 0.0001) and after adjusting for age and sex (OR = 2.18, 95% CI: 1.63-2.91, P < 0.0001) and for multiple confounders (OR = 2.44, 95% CI: 1.67-3.57, P < 0.0001). Subgroup analysis revealed that the association between the RAR and poor prognosis was consistent across all subgroups. Elevated RAR is significantly associated with poor 3-month functional outcomes in patients with AMIS.
