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

Purpose: The purpose of this study was to compare spherical equivalent (SE) and estimated prevalence of myopia in school-age children between Shanghai and Yunnan in China, and to investigate the differences in SE and estimated prevalence of myopia between Han ethnicity and ethnic minorities in Yunnan. Methods: This was a retrospective observational study, which enrolled one primary school and one junior high school in Shanghai, and two primary schools and two junior high schools in Yunnan in 2021. Refraction was measured using autorefractors without cycloplegia. Pearson correlation analysis, Chi-square test and multiple linear regression (MLR) were used for analysis. Results: A total of 2,744 children in Shanghai and 1,769 children in Yunnan were examined, respectively. Less hyperopic SE was observed in Grades 1 and 2 in Shanghai compared to Yunnan (both Conclusion: Spherical equivalent and estimated prevalence of myopia of school-age children in Yunnan are similar to Shanghai. Furthermore, a similar situation exists between Han ethnicity and ethnic minorities.
