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
Myopia is a common visual problem, and the relationship between the subfoveal choroidal thickness (SFCT) and the different degrees of myopia has always been a hotspot in myopia research. This was a prospective longitudinal cohort study. From July 2022 to December 2023,102 (204 eyes) myopic patients from Xinjiang Uygur Autonomous Region Traditional Chinese Medicine Hospital were collected, and 3 groups were low, moderate and high myopia according to spherical equivalent (SE). All patients underwent an ocular basic examination, and the macular subfoveal and peripheral choroidal thickness was measured by enhanced depth imaging optical coherence tomography. Follow-up after 1 year, record relevant data and statistical analysis. There were significant differences in choroidal thickness, SE, and axial length (AL) in the different degrees of myopia at baseline (P < .05), and no differences in corneal curvature (P > .05). At follow-up, the choroidal thickness was significantly different from the low and moderate groups (P < .05), and some loci in the low and moderate groups were significant (P < .05). Choroidal thickness was different between the 3 groups at baseline and at follow-up (P < .05). Overall, SFCT was positively correlated with SE (r = 0.63, P < .05) and negatively with AL (r = -0.62, P < .05). There are different associations between different degrees of myopia. The low myopia group had the thickest choroid in the macular area, the high myopia group the thinnest, and the thinnest nasal side. Myopia increases, and the choroidal thickness becomes thinner. SFCT was negatively correlated with AL, positively correlated with SE in high myopia, and no such relationship between moderate and low myopia. Choroidal thickness is associated with AL and refractive error, suggesting it may serve as a biomarker for monitoring myopic changes in children and adolescents. By comparing the changes of SFCT of different degrees of myopia, analyzing the correlation between AL and choroidal thickness, it provides a basis for exploring the relationship between choroidal thickness and myopia.
