Red Cell Distribution Width-Coefficient of Variation and Its Correlation With Components of Metabolic Syndrome: A Case-Control Study.
Article in Cureus, 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
backgroundChanges in erythrocyte shape caused by oxidative stress and persistent low-grade inflammation associated with metabolic syndrome (MetS) might cause variations in red cell distribution width-coefficient of variation (RDW-CV). This study assessed RDW-CV in MetS patients and looked at how it related to biochemical and clinical indicators. Changes in erythrocyte shape caused by oxidative stress and persistent low-grade inflammation associated with MetS might cause variations in RDW-CV.
methodsThis case-control study was conducted in the general medicine department of Sharda Hospital in Greater Noida between January 2020 and June 2021. Fifty patients between the ages of 18 and 60 who satisfied the diagnostic criteria for MetS were included, along with fifty age- and sex-matched healthy controls. The clinical evaluation included blood pressure checks and anthropometric measurements. Laboratory examinations included complete blood counts (including RDW-CV), fasting and postprandial blood glucose, liver function tests, renal function tests, lipid profiles, and thyroid function testing.
resultsPatients with metabolic syndrome exhibited a significantly higher mean RDW (15.06±1.64% vs. 13.22±1.29%) than healthy controls. RDW-CV showed strong associations with high-density lipoprotein (HDL) cholesterol, serum triglyceride levels, and abdominal circumference. RDW-CV quartiles, however, did not appear to be correlated with any other clinical variables. Greater RDW-CV quartiles were associated with a reduced hazard of metabolic syndrome in male individuals.
conclusionThe mean RDW-CV was significantly greater in patients with MetS, and there were strong correlations with HDL cholesterol, triglycerides, and abdominal circumference. These findings suggest that RDW-CV may be a conveniently available and reasonably priced hematological marker that reflects the metabolic and inflammatory changes linked to metabolic syndrome. To confirm its clinical usefulness, larger prospective investigations are necessary.
