Sotatercept in TBX4 Associated Heritable Pulmonary Arterial Hypertension: A Case Report of a Super Responder.
Article in Pulmonary circulation, 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
Pulmonary arterial hypertension (PAH) is a life-threatening disease of the pulmonary arteries. Progressively increasing pulmonary artery pressure may lead to fatal failure of the right ventricle, necessitating aggressive drug treatment. Sotatercept, a novel drug for PAH-targeted therapy, shows promising results in clinical trials. Nevertheless, efficacy in the heterogeneous PAH population and long-term outcomes have yet to be investigated. This case report illustrates the life-changing effects of sotatercept in a patient with heritable PAH associated with a TBX4 mutation. Our patient faced near immobility, oxygen dependency, and was listed for lung transplantation in November 2023. Following sotatercept administration from July 2024 onward, she started sporting activities and has been removed from the transplantation waiting list. Thereby, this case illustrates an exceptional response to sotatercept in a patient with TBX4-associated heritable PAH. Positive effects persist 1 year after initiation without significant side effects.
