1 · What the graph read from it

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.

2 · The registry

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

objectivesThe aim of the study was to identify the prevalence and risk factors of myopia and high myopia in students from primary school and junior high school in Shandong.

methodsA total of 35,614 subjects completed the visual acuity test, refraction error measurement, and questionnaire in 2019. The visual acuity test was performed using the standard logarithmic visual acuity chart and the refractive error was measured by an automatic refractometer without cycloplegia.

resultsThe average age was 12.38 ± 1.78 years, with 18,501 boys and 17,113 girls. The overall prevalence of myopia and high myopia was 68.02% and 5.90%, respectively, and reached up to 85.54% and 13.13% for the grade 9 students. The risk factors included girls, parental myopic history, time spent doing homework, and less sleep time. Performing eye exercise was significantly associated with a lower risk of myopia. Use of mobile devices and reading while lying down were only related to myopia, not high myopia.

conclusionThe prevalence of myopia and high myopia is at a high level. In addition to genetic factors, continuous close work and a lack of sleep was an important factor associated with children myopia and high myopia.
