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 determine the structural characteristics of the peripapillary sclera in myopic eyes using polarization-sensitive optical coherence tomography (PS-OCT). Methods: Patients with myopia who underwent PS-OCT imaging between April and June of 2023 were studied. The intensity, optic axis, and birefringence of the PS-OCT images were analyzed to determine the configuration of the lamina cribrosa (LC). The direction and arrangement of the scleral collagen fibers in the peripapillary region and scleral ridge were determined. Results: In total, 110 eyes of 59 patients with myopia (mean axial length, 30.00 ± 1.98 mm) were studied. PS-OCT showed that the scleral fibers around the optic nerve were arranged circularly in all eyes, regardless of the presence or size of the peripapillary atrophy. Inner scleral fibers that appeared to penetrate beneath this circular arrangement were detected in 94 eyes (85.5%). There was a Y-shaped split at the point of penetration in 77 eyes (70.0%). The integrity of the circular arrangement and possible presence of penetrating scleral fiber complexes remained intact, even in cases of severe peripapillary scleral deformation. A scleral ridge was identified in 27 eyes (24.5%), and it appeared as a full-thickness protrusion composed primarily of outer scleral fibers. The ridge was consistently located outside the circular arrangement. Conclusions: PS-OCT imaging suggests the possible presence of inner scleral fibers penetrating the peripapillary circular scleral arrangement. These fibers may contribute to peripapillary structural stability and potentially extend toward the LC.
