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

backgroundThis study aimed to explore the trends and prevalence of dental caries in children aged 3 to 5 years in Beijing from 2013 to 2023.

methodsA repeated cross-sectional surveillance study was conducted by analyzing oral examination data derived from the Beijing public health program for children aged 3 to 5 years in Beijing over an 11-year period from 2013 to 2023. The dmft index, the prevalence of dental caries, and the dental caries filling ratio serve as key indicators for assessing the status of deciduous teeth caries.

resultsOverall, the prevalence of dental caries and the dmft index among children aged 3 to 5 years in Beijing exhibited a consistent and gradual downward trend from 2013 to 2023. The dental caries filling ratio among 3-, 4-, and 5-year-old children increased significantly from 2013 to 2019 but decreased in 2023 to below the 2019 level.

conclusionsOver the past 11 years, the prevalence of dental caries among children aged 3 to 5 years in Beijing has exhibited a general downward trend.
