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

backgroundPulmonary vascular changes in postoperative pulmonary artery hypertension (PAH) are similar to those seen in idiopathic PAH. Data are sparse on direct comparative midterm outcomes for these 2 high-risk populations.

methodsPatients with idiopathic or postoperative PAH referred to a large tertiary hospital between June 2005 and July 2019 were retrospectively evaluated.

resultsA total of 364 consecutive patients were studied, including 201 postoperative PAH patients and 163 patients with idiopathic PAH, with a median age of 18.7 (interquartile range 10.0, 31.5) and 7.3 (IQR: 2.9, 18.3) years, respectively. PAH-specific drugs were used in 77.7% of patients; 31.4% received combination therapy. Patients with idiopathic PAH had a shorter 6-mintue walk distance, lower percutaneous oxygen saturation, and higher B-type natriuretic peptide levels than those with postoperative PAH at diagnosis (all

conclusionsPostoperative-PAH patients had better midterm survival compared to patients with idiopathic PAH. Mortality was significant in both PAH groups, reinforcing the need for early diagnosis and optimal individualized management to improve outcomes.
