Income Inequality in Dental Visits Among Chinese Children: Analysis of Longitudinal Data.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimThis study aimed to explore whether income inequality exists in dental visits among children when children/parents were informed they had caries.
methodsThis study used data from a prior longitudinal study carried out in Liaoning Province, China, involving 772 children under the age of five from local kindergartens. Children were clinically assessed for dental caries at baseline, data on dental visits were collected a year later. Logistic regression model was used to analyze the association between dental caries and household income at baseline and dental visits at follow-up, a year later.
resultsIn the logistic regression analysis accounting for age and sex, the results showed that household income and dental caries had significant association with dental visits among Chinese children. Lower household income was negatively associated with dental visits, with those at the lowest income level having lower odds ratio (OR) of 0.27 (95% confidence interval (CI): 0.16, 0.47), and the second lowest income level, with OR of 0.39 (95% CI: 0.22, 0.71) compared to highest-income group. There was a statistically significant association between dental caries at baseline and dental visits in the following year (OR: 1.08, 95% CI: 1.02, 1.15).
conclusionThere were income inequalities in dental visits among children in China, even when they were diagnosed with dental caries. Socioeconomic inequality appears to be a major barrier to dental visits among Chinese children with dental needs.
