Longitudinal changes of refractive error in preschool children with congenital ectopia lentis.
Article in International ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCongenital ectopia lentis (CEL) is a hereditary eye disease which severely impacts preschool children's visual function and development. This study aimed to evaluate the longitudinal changes in spherical equivalent (SE) refractive error in preschool children with CEL.
methodsA retrospective cohort study was conducted at Zhongshan Ophthalmic Center, Guangzhou, China. Medical records of CEL patients under 6-year-old who were diagnosed with Marfan syndrome at the initial visit from January 2014 to March 2022 were collected and were divided into surgery and non-surgery groups. Mean change rate of SE in the two groups was evaluated, and the potential associated factors of SE change rate were investigated by mixed-effect regression model.
resultsA total of 94 preschool patients from 14 provinces of China were included. Among the 42 children of the surgery group, the mean age with standard deviation (SD) was 5.02 ± 0.81 years and patients experienced a myopic shift of -0.05 ± 0.09 D/month in average. The mean age with SD of the 52 children of the non-surgery group was 4.34 ± 1.02 years, and the mean myopic shift was -0.09 ± 0.14 D/month. The mixed-effect regression model identified that higher degree of myopia at baseline was associated with slower myopic shift both in surgery (β = 0.901, 95% CI: 0.822 ~ 0.980, P < 0.001) and in non-surgery group (β = 1.006, 95% CI: 0.977 ~ 1.034, P < 0.001) in CEL patients. Surgical treatment (β = 2.635, 95% CI: 1.376 ~ 3.894, P < 0.001) was associated with slower myopic shift in all participants CEL patients.
conclusionsMyopic progression was slower in the surgery group than in the non-surgery group of CEL. Preschool CEL patients who met the surgical indication are suggested being performed with timely surgery to slow down the myopic progression.
