The metabolism of big endothelin-1 axis and lipids affects carotid atherosclerotic plaque stability - the possible opposite effects of treatment with statins and aspirin.

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
backgroundThe understanding of endothelin's role in carotid plaque instability is limited. We have studied the big endothelin-1 (ET-1) axis and its role in carotid plaque stability in patients undergoing carotid endarterectomy (CEA). The interactions of endothelins with known CVD risk factors were also evaluated.
methodsWe studied 77 patients, who were divided into subgroups based on the optimal cut-off for grey-scale median (GSM), a marker of plaque instability. GSM values < 46.87 were designated as unstable carotid plaque, while GSM ≥ 46.87 were assigned to stable plaque. Twelve people without carotid atherosclerosis served as controls. Big ET-1, ET-1 and ET-1 (1-31) were measured and the endothelin-converting enzyme-1 (ECE-1) and chymase activity were calculated. Clinical and laboratory parameters were also evaluated.
resultsET-1 levels and ECE-1 activity were increased in all patient groups compared to controls (all P < 0.001) - and were higher in patients with unstable plaque than in those with stable plaque (P < 0.01). ET-1 (1-31) did not differ between the groups. ET-1 levels and ECE-1 activity inversely correlated with total cholesterol, LDL-cholesterol, and GSM values, whereas GSM was positively associated with total cholesterol and LDL fractions. Detailed analysis of patients according to the pharmacotherapy used revealed that statins favored ET-1 formation independently of cholesterol-lowering properties, whereas aspirin reduced this effect.
conclusionsET-1 formation is the main pathway of big ET-1 metabolism in patients with carotid atherosclerosis, especially in those with plaque instability. Statins and aspirin appear to have opposing effects on ET-1 formation, suggesting the greater benefit related to plaque stability in patients taking both drugs concomitantly.
