Dural Injury Revealed by 64 Cu-DOTA PET/CT Cisternography and Intraoperative Detection of a Cholesteatoma After a Temporal Bone Gunshot Injury.
Article in Clinical nuclear 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
A 50-year-old man with a history of a gunshot wound to the skull base in 1997 presented with new secretion from a retroauricular skin defect and clinical signs of a cerebrospinal fluid (CSF) leak. MRI was contraindicated due to retained metallic foreign bodies. [ 64 Cu]Cu-DOTA PET/CT cisternography revealed progressive extravasation of CSF tracer from the posterior fossa toward a mastoid defect, consistent with a CSF leak, but no fistula to the skin. Intraoperative findings confirmed the leak and identified a cholesteatoma within the bullet tract. This case illustrates the complexity of temporal bone gunshot injuries and highlights the diagnostic utility of PET/CT cisternography in detecting CSF leaks.
