1 · What the graph read from it

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.

2 · The registry

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

backgroundN-terminal brain natriuretic peptide (NT-proBNP) is a neurohormonal substance secreted mainly by the cardiac myocytes of the left ventricle and to a less degree of the left atrium. The releasing mechanism is induced by an increased wall stress on the base of volume or pressure load of the ventricle. The physiologic actions of BNP are prohibition of the sympathetic activity, vasodilatation, natriuresis, diureses and inhibition of the renin-angiotensin system. Because of its high sensitivity and specifity in relation to the left ventricular incompetence, BNP as well as NTproBNP are well accepted markers of ventricular dysfunction. It was the aim of the study to establish reference values of NT-proBNP serum concentrations throughout childhood, in particular in the newborn age group.

methodsIn a cross sectional study, serum NT-proBNP concentrations were measured by an ElectroChemiLuminescenceImmunoAssay ("ECLIA" Roche) in the umbilical cord blood of 62 healthy full-term neonates and in 222 healthy probands from birth up to the age of 18 years.

resultsThe concentration of NT-proBNP in the cord blood samples ranged from 281 to 2595 pg/ml (mean: 818 pg/ml). There was a significant increase in the first days of life followed by a rapid decrease during the first year and a further gradual decrease throughout infancy; beyond the 10(th) year of age normal adult values were approached.

conclusionsThe knowledge of the normal range of plasma NT-proBNP levels in healthy subjects during childhood serves as a non-invasive marker for differentiation of pathologic conditions such as acute myocarditis, hypertrophic or dilated cardiomyopathy, tachyarrhythmias and pulmonary hypertension.
