Fibroblast Activation Protein Inhibitor Positron Emission Tomography Imaging in Atrial Fibrillation: Current Evidence and Future Perspectives.
Review in Reviews in cardiovascular medicine, 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
Fibroblast activation protein inhibitor (FAPI) positron emission tomography/computed tomography (PET/CT) has emerged as a promising molecular imaging modality for visualizing fibroblast activation and extracellular matrix remodeling. In addition to its established role in oncology imaging, FAPI PET/CT is gaining recognition in the evaluation of cardiovascular disease. Emerging evidence suggests that this technique may provide molecular insights into atrial fibroblast activation and the development of a fibrotic substrate in atrial fibrillation. Meanwhile, related findings from other arrhythmias further support a potential link between myocardial fibroblast activation and electrophysiological remodeling. This review summarizes the current evidence on FAPI PET/CT imaging in atrial fibrillation, discusses related findings in other cardiovascular conditions, and highlights future directions for research in arrhythmia imaging.
