Prevalence and related factors of high myopia among adults aged 50 years and older in Fujian Eye Study.
Article in PloS one, 2026. 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
purposeThis study aimed to assess the prevalence of high myopia and its associated demographic and ocular factors among residents aged 50 and older in Fujian Province, Southeast China.
methodsA population-based cross-sectional eye study was conducted from May 2018 to October 2019, enrolling residents aged 50 and older. Participants completed a questionnaire covering education, income, medical history, and lifestyle habits (including smoking, drinking, and tea consumption). They also underwent physical and ophthalmological examinations measuring height, weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), refraction, intraocular pressure (IOP), and visual acuity (distance and best-corrected). Statistical analysis was performed using Stata software, and a multivariate logistic regression model was employed to identify factors associated with high myopia.
resultsA total of 8,024 residents were included in the study. The overall prevalence of high myopia was 3.85% [95% CI: 3.43%-4.27%]. Multiple logistic regression showed that high myopia was significantly associated with inland residency (OR=0.672, p = 0.037), higher IOP (OR=1.069, p = 0.001) and higher education level (OR=1.645, p < 0.001).
conclusionHigh myopia is prevalent among Chinese adults, affecting 3.85% of the study population. The findings highlight the need for greater investment in accessible eye care services and policies aimed at inland elderly residents, particularly those with higher IOP and higher education level.
