Effectiveness of orthokeratology in myopia control during COVID-19 home confinement in Shanghai: a retrospective study.
Article in BMC ophthalmology, 2025. 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
backgroundMyopia is a growing public health issue, with the COVID-19 pandemic potentially accelerating its progression due to home confinement and increased near work. This study investigates the effectiveness of orthokeratology in controlling myopia during the strict home confinement period in Shanghai in 2022.
methodsWe conducted a retrospective study involving 139 myopic children who used orthokeratology before, during, and after the home confinement period and 91 children as a control group. Axial length (AL) was measured at three time points: before, during, and after home confinement.
resultsThe axial length growth in the orthokeratology group was significantly lower during the home confinement period compared to the control group (0.102 ± 0.105 mm/6 months vs. 0.199 ± 0.165 mm/6 months, p < 0.001). No significant differences were observed in axial length growth before, during, and after home confinement within the experimental group.
conclusionsOrthokeratology remains effective in controlling myopia progression even during adverse conditions like home confinement, offering an important strategy for myopia control in high-risk environments.
