Lung Injury After Balloon Pulmonary Angioplasty for CTEPH: Histopathologic Findings and Management Implications.
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
Balloon pulmonary angioplasty (BPA) has emerged as a guideline-recommended therapy for surgically inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Lung injury occurs in approximately 6% of BPA sessions and is the leading cause of procedure-related mortality. While lung injury post-BPA has recently been associated with vascular injury and hemorrhage, pathologic evidence is lacking regarding whether injury is uniformly hemorrhagic or whether a permeability-mediated pattern, such as seen in reperfusion edema, predominates in some cases. We present a case of severe BPA-associated lung injury resulting in mortality, report the first histopathologic characterization of the parenchymal injury pattern in this setting, and describe how these findings informed successful rescue veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in a second case.
