Effect of supplemental oxygen therapy on 6-min walk distance in patients with pulmonary arterial hypertension living at 2850 m: a randomised, crossover trial.
Article in ERJ open research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Patients with pulmonary arterial hypertension (PAH) who permanently live at high altitude (>2500 m) face particular challenges due to hypobaric hypoxia, which may exacerbate pulmonary hypertension and impair exercise capacity. We therefore investigated the effect of low-dose supplemental oxygen therapy (SOT) on 6-min walk distance (6MWD) in high-altitude residents diagnosed with PAH. Methods: Adults diagnosed with PAH who permanently live at >2500 m performed two 6MWD tests, once with SOT (1-2 L·min Results: 28 patients (86% women, mean±sd age 45±12 years, resting Conclusion: In high-altitude residents diagnosed with PAH, low-dose SOT as commonly prescribed
