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.
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
objectivesThis study aims to understand the prevalence and treatment status of dental caries in preschool children aged 3-5 years in China among the past five years.
methodsDatabases including CNKI, WanFang data, VIP, MEDLINE, EMBASE were systematically searched for the epidemiological literature of dental caries in preschool children in China from 2017 to 2022 for Meta-analysis. Subgroup analysis was carried out by sex, age, geographical region, ethnology, and residence.
resultsThe Meta-analysis enrolled 27 literatures, including 72 788 preschool children; of which, 38 344 children had dental caries. The merged prevalence of dental caries in preschool children was 59.3% (95%CI: 54.6%-63.9%), and the merged filling rate of caries was 5.7% (95%CI: 2.5%-8.8%). In the subgroup analysis, the merged prevalence rates of caries in children aged 3, 4, and 5 years were 46.9% (95%CI: 42.5%-51.4%), 59.0% (95%CI: 55.1%-62.8%), and 67.3% (95%CI: 62.5%-72.2%), respectively, and the difference was significant. In addition, significant differences were found among different regions. The merged prevalence of dental caries in preschool children was the highest in northwest China (68.6%, 95%CI: 55.5%-81.8%) and the lowest in central China (49.1%, 95%CI: 47.3%-51.0%). The merged prevalence of dental caries was not significantly different among preschool children of different genders, ethnicities, and residence.
conclusionsThe prevalence of dental caries in preschool children aged 3-5 years in China is high and continuously increases. The oral health of preschool children should be comprehensively strengthened, and a three-level strategy should be implemented to prevent diseases.
