Association between myopia and relative peripheral refraction in children with monocular Tilted disc syndrome.

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
backgroundThis study aimed to investigate the refractive error and relative peripheral refraction in pediatric patients with monocular tilted disc syndrome.
methodsThis single-center, prospective, cross-sectional, observational study included 49 patients from the Pediatric Ophthalmology Department of the Second Hospital of Hebei Medical University aged 5-17 years with monocular tilted disc syndrome. Eyes with tilted optic discs formed the study group, and contralateral eyes with normal discs served as controls, with mean spherical equivalents of - 3.24 D and - 0.47 D, respectively. Best-corrected visual acuity, spherical equivalent, axial length, tilt ratio, defined as the ratio of maximum to minimum disc diameters, and relative peripheral refraction, assessing myopia-related defocus were compared between groups. Pearson's correlation analysis assessed associations between optic disc tilt and spherical equivalent, axial length, and the total refraction difference value.
resultsTilted optic discs were associated with significantly greater myopia (- 3.24 ± 1.83 D in tilted eyes and - 0.47 ± 0.72 D in non-tilted eyes, P <.001), longer axial length (24.59 ± 1.04 mm in tilted eyes and 23.45 ± 0.78 mm in non-tilted eyes, P <.001), and a higher tilt ratio (1.43 ± 0.05 in tilted eyes and 1.14 ± 0.04 in non-tilted eyes, P <.001). Discrepancies between tilted and non-tilted eyes were observed in the superior, inferior, and nasal quadrants, and the total refraction difference value (P <.001). In eyes with tilted disc syndrome, a negative correlation was found between the total refraction difference value and the spherical equivalent (P <.001). The tilt ratio of optic disc eyes was significantly greater than that of contralateral eyes and was negatively correlated with the spherical equivalent. There was a positive correlation between the tilt ratio and axial length (P <.001).
conclusionsPediatric patients with monocular tilted disc syndrome exhibited longer axial lengths, more myopic spherical equivalent, and more positive relative peripheral refraction. A greater tilt ratio is associated with larger relative peripheral refraction and axial length, corresponding to more severe myopia.
