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
purposeThis study assessed the diagnostic potential of chromatic pupil campimetry (CPC) using relative maximal constriction amplitude (relMCA), pupillary light response (PLR) latency, and pupillary escape to differentiate optic neuropathies (ON) from healthy individuals and identify specific ON subtypes.
methodsCPC testing used red and blue stimuli at central (0°) and peripheral (20°) locations to measure relMCA, latency, and pupillary escape. Patients with various ON etiologies, including glaucoma (n = 20), optic nerve compression by meningioma (n = 18), chiasm compression (n = 4), Leber hereditary optic neuropathy (LHON; n = 4), and autosomal dominant optic atrophy (ADOA; n = 3), were tested. Linear mixed-effects models and post hoc Tukey tests were used to analyze differences across subgroups of ON etiologies and a healthy control group (n = 40), regarding signal eccentricities and locations.
resultsPupillary escape was significantly higher in ON patients during central red stimulation (p = 0.0007). Glaucoma and meningioma groups showed reduced relMCA and prolonged latency for both stimuli compared to controls (p < 0.0001 to p = 0.0058). RelMCA during blue stimulation was lower in glaucoma patients than in ADOA (p = 0.0183). LHON patients exhibited significantly prolonged PLR latency during blue stimulation compared to healthy (p = 0.0284).
conclusionCPC effectively distinguished glaucoma and meningioma from healthy controls but was less reliable for differentiating ON subtypes. Our results indicate, that central pupillary escape is associated with inner retinal dysfunction.
