Cardiopulmonary Exercise Testing With Forehead and Popliteal Oximetry in Evaluating Efficacy of Reverse Potts Shunt.
Article in JACC. Case reports, 2025. 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
Reverse Potts shunt (rPS) is a surgical procedure that creates an anastomosis between the left pulmonary artery and descending aorta to decompress the right ventricle in suprasystemic pulmonary arterial hypertension (PAH). In this paper, we introduce a unique procedure combining cardiopulmonary exercise testing with forehead and popliteal oximetry to evaluate the efficacy of the rPS. Our study involved tests on 4 patients with PAH who had the shunt in place. We found that the level of oxygen saturation in the popliteal artery decreased during exercise and correlated with the rPS efficacy and the overall clinical outcome. In conclusion, we demonstrate a simple, noninvasive technique for evaluating patency and function of rPS in patients with suprasystemic PAH.
