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

purposeBendopnea is a recently reported novel symptom in patients with heart failure (HF) defined as shortness of breath when bending forward. It has been demonstrated that bendopnea is associated with advanced symptoms and worse outcomes. The aim of this study was to assess the presence of bendopnea and its clinical importance with regards to functional status, hemodynamic and echocardiographic characteristics in outpatient pulmonary arterial hypertension (PAH) patients.

methodsWe conducted this prospective observational study of 53 patients who were admitted to our PAH clinic for routine control visits. We determined the presence of bendopnea and analyzed hemodynamic parameters, World Heart Organization (WHO) functional class, transcutaneous oxygen saturation, 6-minute walking distance (6-MWD), N-terminal pro-brain natriuretic peptide (NT-proBNP) and right ventricular (RV) function indicators in patients with and without bendopnea.

resultsBendopnea was present 33.9% of the PAH patients. The mean age was higher in the patients with bendopnea than in those without bendopnea, but the difference was not significant (p = 0.201). The patients with bendopnea had a lower 6-MWD and higher NT-proBNP level (p < 0.001), and worse WHO functional class symptoms (p = 0.010). Mean right atrial pressure, pulmonary artery pressure, and pulmonary vascular resistance were higher in the patients with bendopnea. The patients with bendopnea had a more dilated RV end-diastolic diameter and lower tricuspid annular plane systolic excursion value (p < 0.001 and p = 0.001, respectively).

conclusionsBendopnea was associated with worse functional capacity status, hemodynamic characteristics and RV function in our outpatient PAH patients.
