NT-proANP levels in peripheral and cardiac circulation.

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
backgroundRecent studies have reported an association between N-terminal atrial natriuretic peptide (NT-proANP) and the progression of atrial fibrillation (AF). However, NT-proANP levels in peripheral and cardiac circulation in AF patients and in non-AF individuals need to be defined. The aims of the current study are (1) to analyze NT-proANP levels in peripheral and cardiac circulation in AF patients and (2) to compare NT-proANP levels in individuals with and without AF.
methodsWe recruited AF patients who were undergoing their first AF catheter ablation and non-AF individuals. Blood plasma samples taken from the femoral vein and the left atrium (LA) were collected before AF ablation in the AF patients and from the cubital vein in the non-AF controls. Low voltage areas (LVAs) were determined using high-density maps during catheter ablation and defined as < 0.5 mV.
resultsThe study included 189 AF patients (64 ± 10 years, 59% male, 61% persistent AF, 30% LVAs) and 26 non-AF individuals (58 ± 10 years, 50% male). Patients with AF were significantly older and had larger LA (p < 0.05). Compared to non-AF controls, peripheral and cardiac NT-proANP levels were significantly higher in AF patients without and with LVAs (median 5.4, 10.5, 14.8 ng/ml, respectively, p < 0.001). In multivariable analysis, NT-proANP (OR 1.238, 95% CI 1.007-1.521, p = 0.043) remained significantly different between non-AF individuals and AF patients. In AF, NT-proANP levels were significantly higher in the cardiac blood samples than in the peripheral blood (median 13.0 versus 11.4 ng/ml, p = 0.003). The ability to predict LVAs was modest when using cardiac NT-proANP (AUC 0.661) and peripheral NT-proANP (AUC 0.635), without statistical difference (p = 0.937).
conclusionsNT-proANP levels are higher in individuals with AF than in controls and are more pronounced in progressed AF. Elevated cardiac and peripheral NT-proANP levels similarly predict LVAs.
