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 investigate the prevalence of deciduous dental caries in preschool children aged 36-71 months as well as the eruption and caries status of permanent teeth in children aged 60-71 months in Guangzhou city, providing references for oral health work.

settingThe study was conducted in 34 kindergartens in the central and non-central urban areas of Guangzhou city.

participants14 883 preschool children aged 36-71 months in Guangzhou city were included in the ultimate analysis.

main outcome measuresThe prevalence of dental caries and other indicators of deciduous teeth, eruption and caries status of permanent teeth in children aged 60-71 months.

resultsThe prevalence of dental caries in children aged 36-47 months, 48-59 months and 60-71 months were 41.6% (95% CI: 40.1%, 43.1%), 57.1% (95% CI: 55.8%, 58.5%) and 65.2% (95% CI: 64.0%, 66.4%), respectively. Mean decayed-missing-filled teeth increased with age, with differences between genders and areas. The percentage of permanent first molars and central incisors eruption in children aged 60-71 months differed, and caries conditions varied.
