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
introductionN-terminal pro-B-type natriuretic peptide (NT-proBNP) can be a marker of left ventricle (LV) pressure overload in hypertrophic cardiomyopathy (HCM). The different clinical characteristics of HCM might correspond to the degree of NT-proBNP increase.
aimThis study aimed to establish whether the left atrium (LA) dimension, left ventricle outflow tract (LVOT) gradient, and pulmonary hypertension influence NT-proBNP serum levels in patients with HCM. MATERIAL AND
methodsIn 62 HCM patients (32 males and 30 females, mean age 31 ±11 years), echocardiography with LV outflow tract gradient provocation was performed using natural stimuli > 30 mm Hg (NOHCM - 36 patients, POHCM - 12 patients, HOCM - 14 patients).
resultsSmaller LAD was associated with a lower NT-proBNP/ULN level (
conclusionsIncreased NT-proBNP/ULN is positively associated with larger LAD and LAA, while elevated NTproBNP is only associated with larger LAA. The highest levels of both NT-proBNP and NTproBNP/ULN were associated with HOCM and pulmonary hypertension, whereas biomarker levels were comparably lower in both the POHCM and NOHCM.
