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
background and purposeThe basis for an optimal therapy of cardiopulmonary diseases is the assessment of an early diagnosis. This implies an evaluation of possible differential diagnoses of acute dyspnea. In numerous studies, natriuretic peptides were characterized as additional, meaningful parameters for the assessment of left ventricular function. Current studies could demonstrate that surfactant proteins B (SP-B) and D (SP-D) are of importance for the differentiation of patients with acute dyspnea. The aim of this study was to compare the values of NT-proBNP (N-terminal brain natriuretic peptide) and surfactant proteins for the assessment of a final diagnosis in patients with acute dyspnea. PATIENTS AND
methodsNT-proBNP, SP-B and SP-D were measured in 81 patients with acute dyspnea in the emergency room and were correlated with clinical and echocardiographic parameters with respect to the final diagnosis. For this, patients were classified with respect to clinical and echocardiographic parameters in different subgroups concerning the final diagnosis of acute dyspnea.
resultsIn patients with a cardiac origin of acute dyspnea, plasma levels of NT-proBNP were significantly higher as compared to patients with a noncardiac diagnosis (p = 0.04). SP-D was highest in patients with a cardiac origin of acute dyspnea, but after performing regression analysis it seems to be of less importance for the differential diagnosis of acute dyspnea as compared to NT-proBNP. SP-B plasma levels were not different between the four subgroups.
conclusionNT-proBNP is of importance for the differential diagnosis of acute dyspnea. Although SP-D shows similar changes of plasma levels between the four subgroups, it seems to be of less importance for the differential diagnosis of acute dysnea. SP-B occurs to be of no relevance for the differentiation between cardiac and noncardiac origin of acute dyspnea.
