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
Red blood cell distribution width (RDW) has recently been recognized as a novel biomarker associated with various cardiovascular conditions. This study aims to investigate the relationship between RDW and carotid-femoral pulse wave velocity (cfPWV) in a southern Chinese population. A total of 4916 patients were initially enrolled from the First Affiliated Hospital of Fujian Medical University between January 2016 and December 2022. Based on the criteria of inclusion and exclusion, 2830 patients were included in this study. Body weight, height, and blood pressure were measured, and clinical biochemical tests were recorded. cfPWV was assessed using a non-invasive automatic device. Spearman's correlation analysis, generalized linear regression analysis, multivariable logistic regression, and stratified analysis were conducted to assess the correlation between RDW and cfPWV. Participants were stratified into four subgroups based on RDW quartiles: Q1 (RDW ≤ 12.80%), Q2 (12.80% < RDW ≤ 13.40%), Q3 (13.40% < RDW ≤ 14.10%), and Q4 (RDW > 14.10%). A significant increase in age, systolic blood pressure, cfPWV, and HbA1c levels was observed with higher RDW quartiles. Both Spearman's correlation analysis and generalized linear regression analysis revealed a significant association between RDW and cfPWV. Specifically, compared to the lowest quartile, the risk of cfPWV≥10 m/s increased by 56% in the highest quartile (odds ratio = 1.564, p < 0.001). This correlation persisted particularly among the elderly, hypertensive patients who were not taking medication, and those who were taking medication but had poor control. The plasma RDW level was significantly associated with cfPWV in a southern Chinese population, particularly among older adults and individuals with hypertension, suggesting RDW as a potential marker for arterial stiffness.
