Association of Brachial-Ankle pulse pressure with coronary artery stenosis severity: A sex-specific cross-sectional study in Chinese adults.
Article in PloS one, 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
objectivesTo investigate the association between brachial and ankle pulse pressure and the severity of coronary artery stenosis, as well as to explore sex-specific differences in these associations.
methodsA total of 218 patients who attended a tertiary hospital in China from 1 July 2023-31 January 2024 were selected for the study. The brachial artery pulse pressure, ankle artery pulse pressure, degree of coronary artery stenosis, and the number of major vascular lesion branches were standardized and measured. Multiple logistic regression and receiver operating characteristic curves were employed for analysis.
resultsPulse pressure values at all four measurement sites (left and right brachial, left and right ankle) were significantly higher in the severe coronary stenosis group (T3) compared with the mild stenosis group (T1; all P < 0.001). Multivariate logistic regression analysis showed that left brachial pulse pressure (LPP) was independently associated with severe coronary stenosis (OR: 0.048, 95% CI: 0.010-0.227, P = 0.01). ROC analysis revealed that LPP had favorable predictive performance for severe coronary stenosis, with AUC values of 0.862 in men and 0.854 in women. Gender differences were observed in ankle pulse pressure: right ankle PP showed numerically higher AUC values in men (0.847), while left ankle PP showed numerically higher AUC values in women (0.842).
conclusionDepending on gender and the patient's specific condition, brachial and ankle pulse pressure are critical in assessing coronary stenosis. Site-specific pulse pressure measurements may help identify patients at higher risk of coronary stenosis, enabling effective interventions to better safeguard their cardiovascular health.
