Red Blood Cell Distribution Width and Neutrophil-to-Lymphocyte Ratio as Markers of Cardiovascular Disease and Vascular Calcification in Chronic Kidney Disease: A Large Cohort Study.
Article in Metabolites, 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
BACKGROUND/
objectivesCardiovascular disease (CVD) in chronic kidney disease (CKD) arises from a multifaceted interplay of pathophysiological processes, including chronic inflammation, oxidative stress (OS), and accelerated vascular calcification (VC). Red blood cell distribution width (RDW) and the neutrophil-to-lymphocyte ratio (NLR) have emerged as simple, inexpensive, and readily available hematological indices that may capture these underlying disturbances. As such, they hold promise as accessible biomarkers for stratifying cardiovascular risk in patients with CKD.
methodsThis cross-sectional study enrolled 497 patients, comprising 477 with CKD across all stages and 20 controls. We evaluated the associations of RDW and NLR with both traditional and non-traditional cardiovascular risk factors, as well as with serum calcification propensity (T50). Spearman's correlation and multivariable regression analysis were used to assess these relationships.
resultsBoth RDW and NLR were significantly elevated in patients with established CVD (
conclusionsRDW and NLR strongly reflect the burden of inflammation, metabolic disturbance, and vascular dysfunction in patients across the CKD spectrum. The consistent associations with impaired calcification defense and with established cardiovascular risk markers underscore the potential value as accessible indicators of cardiovascular vulnerability in CKD. These findings support incorporating RDW and NLR into routine risk assessment and highlight T50 as a mechanistically relevant determinant of hematologic inflammation profiles.
