Supplemental Oxygen Decreases Cardiac Effort in Pulmonary Arterial Hypertension.
Article in Pulmonary circulation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
In this single-blind, crossover pilot study, supplemental oxygen at 2 L/min during 6-min walk test reduced Cardiac Effort in patients with pulmonary arterial hypertension, while 6-min walk distance remained unchanged. This decrease suggests improved physiology for an unchanged workload. Continuous electrocardiogram heart rate monitoring adds considerable value to the 6-min walk.
