A case with bilateral C-shaped autofluorescence in retinal degeneration.

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
Purpose: To report a case of a 19-year-old male with Optic Atrophy-13 (OPA13) associated with a de novo heterozygous missense variant in the single-strand DNA-binding protein 1 ( Observations: A 19-year-old male exhibited poor visual acuity, pale optic discs, vessel attenuation, and peripheral pigmentary changes. FAF imaging revealed a bilateral double C-shaped hyper-autofluorescent ring, which was not frequently observed. Optical coherence tomography (OCT) showed retinal thinning and ellipsoid zone disruption, while electroretinography (ERG) indicated cone-rod dystrophy. Genetic testing identified a pathogenic Conclusions and importance: This report highlights a novel retinal feature-a double C-shaped autofluorescent ring-associated with OPA13, potentially serving as a diagnostic marker for the disease. The findings emphasize the role of genetic testing in diagnosing OPA13 and distinguishing it from other retinal and optic neuropathies. Recognition of this feature could enhance early diagnosis and management strategies for patients with suspected OPA13.
