Paediatric myopia shift during the COVID-19 pandemic home quarantine: a systematic review and meta-analysis.
Synthesis in BMJ paediatrics open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundOutdoor activities were restricted during the COVID-19 outbreak, although digital learning grew. Concerns have been raised about the impact of these environmental changes on myopia status. This research aimed to examine myopia shift during the COVID-19 pandemic and offer the community evidence-based data.
methodsThe literature search was undertaken in PubMed, SCOPUS, Science Direct, Web of Science and Google Scholar databases on published papers before 17 May 2022. The main outcome was mean spherical equivalent refraction (SER) before, at the onset and at the end of follow-up during the COVID-19 pandemic.
resultsAmong 518 articles, 10 studies were included in the meta-analysis. The mean SER differences during the COVID-19 pandemic follow-up (mean follow-up time was 10 months) compared with before the pandemic was 0.15 dioptre (D) (95% CI -0.39 to 0.69, p=0.58). After age adjustment using meta-regression, the mean SER differences during the COVID-19 follow-up compared with before the pandemic was - 0.46 D (95% CI -0.59 to -0.34, p<0.001). Over the mean follow-up time during the COVID-19 pandemic, the SER mean difference was -0.55 D (95% CI -0.78 to -0.32, p<0.001), showing that the mean SER had decreased significantly during the COVID-19 pandemic. The mean SER differences in myopic patients before COVID-19 compared with during the pandemic follow-up was -0.49 D (95% CI -0.53 to -0.45, p=0.00). So the prior pandemic myopic patients became more myopic during the pandemic follow-up time.
conclusionDuring home quarantine, the mean SRE shifting in paediatrics accelerated. This phenomenon should be given more attention by policymakers, eyecare experts, educators and parents.
