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

Background: The course of pulmonary arterial wedge pressure (PAWP) during exercise in patients with pulmonary arterial or chronic thromboembolic pulmonary hypertension (PAH/CTEPH), further abbreviated as pulmonary vascular disease (PVD), is still unknown. The aim of the study was to describe PAWP during exercise in patients with PVD. Methods: In this cross-sectional study, right heart catheter (RHC) data including PAWP, recorded during semi-supine, stepwise cycle exercise in patients with PVD, were analysed retrospectively. We investigated PAWP changes during exercise until end-exercise. Results: In 121 patients (59 female, 66 CTEPH, 55 PAH, 62±17 years) resting PAWP was 10.2±4.1 mmHg. Corresponding peak changes in PAWP during exercise were +2.9 mmHg (95% CI 2.1-3.7 mmHg, p<0.001). Patients ≥50 years had a significantly higher increase in PAWP during exercise compared with those <50 years (p<0.001). The PAWP/cardiac output (CO) slopes were 3.9 WU for all patients, and 1.6 WU for patients <50 years and 4.5 WU for those ≥50 years. Conclusion: In patients with PVD, PAWP increased slightly but significantly with the onset of exercise compared to resting values. The increase in PAWP during exercise was age-dependent, with patients ≥50 years showing a rapid PAWP increase even with minimal exercise. PAWP/CO slopes >2 WU are common in patients with PVD aged ≥50 years without exceeding the PAWP of 25 mmHg during exercise.
