The association between subfoveal choroidal thickness and refractive error in Taiwanese children: A cross-sectional study.

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
purposeThe aim was to analyze the association of subfoveal choroidal thickness (SFCT) with age, best-corrected visual acuity, refractive error, and axial length in Taiwan pediatric population.
methodsA total of 374 eyes in 187 children were enrolled in this retrospective cross-sectional comparative study, who underwent examinations of best-corrected visual acuity (BCVA), cycloplegic refraction, and axial length (AL). Subfoveal choroidal thickness was assessed utilizing spectral domain enhanced depth imaging optical coherence tomography (EDI-OCT), with measurements taken at the subfovea, defined as the distance from the retinal pigment epithelium to the chorioscleral border.
resultsThe mean age was 5.6 ± 1.9 years (range 2-16 years). The cycloplegic spherical equivalent refractive error was between + 7.25 and - 15.25 diopters (D) and cycloplegic sphere power was between + 8.25 and - 11.5 diopters (D). The mean SFCT was 299.0 ± 69.80 μm. The mean axial length was 22.87 ± 1.29 mm. In univariate analysis, SFCT had significant positive correlations with spherical equivalent (SE) and sphere power (p < 0.05) and significant negative correlations with age, cylinder power, and axial length (p < 0.05). However, after adjusting in the multivariate regression analysis, spherical equivalent, sphere power and age were not independently associated with SFCT. In multivariate analysis, lower cylinder power and longer axial length have significant correlations with thinner SFCT. The relationship between best-corrected visual acuity and SFCT was not significant in both analyses.
conclusionsThis study showed that mean subfoveal choroidal thickness was 299.0 ± 69.80 μm among Taiwanese children. The SFCT was thinner in myopic, longer axial length, and lower cylinder power eyes.
