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

Pulmonary hypertension complicating left heart disease (PH-LHD) is associated with increased morbidity and mortality, especially in patients who develop combined pre- and post-capillary PH (Cpc-PH). Mechanisms underlying PH-LHD are incompletely understood, particularly for individuals with preserved left ventricular ejection fraction (LVEF). We hypothesized that transpulmonary concentrations of biomarkers representing signaling pathways with known effects on the pulmonary circulation could provide insight into the molecular etiology of PH-LHD in patients with preserved LVEF. Blood samples were collected from the pulmonary artery (PA) and wedge positions of outpatients with normal LVEF referred for right heart catheterization. Hemodynamic tracings were reviewed to classify patients as "no PH" (n = 23) or "PH-LHD" (n = 22). A biomarker's transpulmonary ratio (TPR) was calculated as the quotient of wedge and PA concentrations. The TPR of endothelin 1 (ET-1) was elevated in Cpc-PH (n = 10) compared to no PH or isolated post-capillary PH (Ipc-PH, n = 12); cAMP and cGMP TPRs were not different among groups. Higher ET-1 TPR in Cpc-PH was due to increased wedge ET-1 concentration. Pulmonary vascular resistance (PVR) strongly correlated with wedge ET-1 exclusively in Cpc-PH patients. In patients with normal LVEF and Cpc-PH, ET-1 TPR is higher, due to elevated wedge ET-1, compared to those without PH or with Ipc-PH. Strong correlation between PVR and wedge ET-1, observed only in the Cpc-PH group, may suggest increased pulmonary vascular responsiveness to ET-1 in these patients. These findings implicate elevated pulmonary ET-1 as a marker of, and a potential contributor to, development of Cpc-PH in this population.
