Student Assessments of Early Childhood Caries in Some Informal Settlements of Cape Town: A 10-Year Series of Cross-Sectional Studies.
Article in Public health challenges, 2025. 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
Aim: To assess Early Childhood Caries by measuring the dmft, Significant Caries Index (SiC), pufa, and caries-free status in informal settlements outside Cape Town, South Africa over a 10-year period. Method: A series of cross-sectional studies over a 10-year period (2009-2019). Surveys were carried out in preschools in informal settlements. A total of 5090 children aged from 1 to 5 years of age were examined. Results: For 1- to 3-year-olds, the mean dmft was 4.33 ± 1.55, and for 4- and 5-year-olds, it was 6.34 ± 1.48. The difference in dmft for 1- to 3-year-olds increased but did not differ statistically between 2009 and 2019. For 4-5 years old, there was an increase over time. For 1- to 3-year-olds, the mean pufa was 0.34 ± 0.28, and for 4- to 5-year-olds, it was 0.63 ± 0.59. For 1- to 3- and for 4- to 5-year-olds, there was a statistically significant, lower pufa 2009-2019. For 1- to 3-year-olds, the mean SiC was 11.0 ± 2.35, and for 4- to 5-year-olds, it was 12.05 ± 1.89. There was a difference in SiC for 1-3 and for 4- to 5-year-olds, which was higher but did not differ statistically 2009-2019. Among 1- to 3-year-olds, 32.1% were assessed as caries-free. Among 4- to 5-year-olds, 16.0% were caries-free. There was a statistically significant, lower number of caries-free 1- to 3-year-old and 4- 5-year-old children 2009-2019. Conclusions: The mean dmft has been found to be continuously high from 2009 to 2019. The SiC score remained unchanged, whereas pufa was significantly lower. The frequency of caries-free children was lower over time.
