Dietary patterns and oral health practices among primary school children aged 6-15 years in urban informal settlements of Eldoret City, Kenya.

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
backgroundDental caries remains one of the most prevalent chronic conditions among school-aged children, disproportionately affecting those in informal settlements where dietary risks and preventive oral health services are limited.
aimThis study assessed dietary patterns, oral hygiene practices, and their association with dental caries among primary school children aged 6-15 years in informal settlements of Eldoret City in Uasin Gishu County, Kenya.
methodsThe study adopted a school-based cross-sectional design and involved 407 primary school children selected using proportionate stratified random sampling. Data was collected using a validated and pretested structured questionnaire, while clinical oral assessment was based on WHO field guidelines for the examination of dental caries. Data was analyzed using SPSS v.26. Chi-square tests assessed associations, and bivariate and multivariate logistic regression models were used to identify independent dietary patterns and oral hygiene practices associated with dental caries.
resultsOut of 407 children, 55.3% were females, and their average mean age was 12.15 ± 2.98 years. The prevalence of dental caries was 26.0% (95% CI: 21.8-30.3). Daily consumption of sugary foods and beverages and suboptimal oral hygiene practices were relatively high. Multivariate logistic regression models revealed daily intake of biscuits, cakes, sweet pies, and buns (AOR = 2.31; 95% CI: 1.36-3.74; p = 0.004), daily consumption of sweets and candy (AOR = 2.42; 95% CI: 1.35-3.91; p = 0.006), brushing less than twice daily (AOR = 2.92; 95% CI: 1.18-3.87; p = 0.023), and not using fluoride toothpaste (AOR = 1.83; 95% CI: 1.12-2.61; p = 0.043) were independently associated with higher odds of dental caries among primary school children.
conclusionIntegrated school- and community-based prevention strategies targeting dietary patterns and oral hygiene promotion are urgently needed to reduce preventable oral health inequities among vulnerable schoolchildren.
