Copeptin constitutes a novel biomarker of degenerative aortic stenosis.

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
Copeptin is a new biomarker of cardiovascular diseases. Its diagnostic value in degenerative aortic valve stenosis (AS) with preserved left ventricle systolic function is unknown. We aimed to assess the association of serum copeptin levels with AS severity and coexistence of coronary artery disease (CAD). Sixty-four patients with AS and preserved left ventricle systolic function including 40 with severe degenerative AS (group sAS, effective orifice area EOA = 0.67 cm(2)) and 24 with moderate degenerative AS (group mAS, EOA = 1.40 cm(2)) were enrolled into the study. Twenty-three patients without AS and heart failure, matched for age, sex, and CAD occurrence served as the control group (group C). Serum levels of copeptin and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured using enzyme-linked immunosorbent assay. The mean serum copeptin concentrations were significantly higher in patients with AS: sAS (405 pg/ml) and mAS (351 pg/ml; sAS vs mAS P < 0.05), compared with group C (302 pg/ml, P < 0.05). Serum copeptin levels correlated inversely with EOA (r = -0.55; P < 0.001) in AS patients. There was no correlation between copeptin and NT-proBNP or association with the coexisting CAD. Receiver-operating characteristics analysis showed that copeptin was a good marker of severe/moderate AS (sensitivity 71 %; specificity 87 %), with the optimized cut-off value of 354 pg/ml. Serum copeptin concentration constitutes a novel biomarker of degenerative AS. Coexisting CAD does not interfere with copeptin level.
