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

objectiveTo describe the prevalence of myopia and pre-myopia among preschool children aged 5-6 years in ten provinces or municipalities (hereinafter referred to as province) of China, and to provide a reference for the prevention and control of myopia, and the allocation of related health resources.

methodsConvenience sampling was used to select preschool children aged 5-6 years from 21 cities in 10 provinces (including 8 provinces and 2 municipalities) in China. Cycloplegic autorefraction was conducted. The distribution of myopia and pre-myopia was described using frequencies and percentages. The Chi-square test was used to compare the differences in the prevalence of myopia and pre-myopia between regions with different varying economic development levels and between boys and girls, with a significance level of α=0.05.

resultsA total of 12 926 preschool children aged 5-6 years were surveyed. The myopia prevalence was 5.5%, and the overall prevalence of myopia and pre-myopia was 43.4%. Boys had higher rates of myopia and overall prevalence of myopia and pre-myopia than girls (5.7%

conclusionThe prevalence of myopia and pre-myopia among preschool children aged 5-6 years is relatively high. Boys show higher overall prevalence of myopia and pre-myopia than girls, but there is no significant difference in the prevalence of myopia. There is no consistent association between the level of economic development and the incidence of myopia and pre-myopia in each province.
