Femoral artery plaque: A simple ultrasound clue for severe coronary stenosis.
Article in World journal of cardiology, 2025. 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
backgroundWith rising angiography costs and risks, we explored whether a 5-minute femoral ultrasound can predict patients that actually require angiography.
aimTo detect associations between atherosclerosis of peripheral arteries and coronary stenosis in patients with coronary heart disease (CHD).
methodsThe study included a total of 218 patients (63 ± 10.9 years of age; 54% male) with CHD subjected to coronary angiography and routine diagnostic assessment, including ultrasound imaging to assess the extent of peripheral atherosclerotic lesions. Receiver operating characteristic analysis and binomial logistic regression were used to detect the associations.
resultsWe demonstrated for the first time that the presence of atherosclerotic plaque with ≥ 70% stenosis in femoral arteries was associated with significant coronary stenosis, with 93% sensitivity and 90% specificity, and thus can be used as an additional diagnostic marker for coronary stenosis. The data indicated associations between femoral artery atherosclerosis and atherosclerotic lesions of coronary arteries, with a high correlation coefficient
conclusionFor resource-limited clinics, our findings suggest skipping carotids - femoral ultrasound alone may suffice to rule out severe CHD. Ultrasound imaging femoral artery atherosclerosis provides a simplified approach for patient stratification.
