Effectiveness of nutrition counseling on reducing sugar intake amount and frequency: A randomized clinical trial.
Article in Journal of education and health promotion, 2026. 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
backgroundDental caries is a widespread oral health issue with significant medical and socioeconomic consequences. Despite preventive measures, nearly 90% of US adults have experienced caries, disproportionately affecting lower-income and minority populations. While fluoride use and oral hygiene practices help mitigate caries development, dietary sugar remains a primary driver. However, nutrition counseling in dental settings remains underutilized. MATERIALS AND
methodsThis randomized, single-center, two-group clinical study assessed the impact of Stephan's curve-based nutrition counseling on snacking frequency and added sugar consumption over 2 weeks. One hundred adult participants were randomized into an intervention group receiving personalized nutrition counseling or a control group receiving no counseling. The nutrition counseling focused on reducing both the frequency of snacking and the amount of added sugar consumed during snacks. Participants used an app that calculates the amount of added sugar consumed. Additionally, the Stephan's curve was utilized as a visual tool to demonstrate how sugar or carbohydrate intake causes a drop in pH below the critical threshold. Examiners assessed the caries experiences expressed as decayed, missing, or filled teeth (DMFT) of participants at baseline and at the 2-week follow-up visit. Participants logged their snacking frequency and sugar consumption daily. Statistical analysis compared pre- and post-intervention data using t-tests and Random Forest modeling.
resultsThe intervention group significantly reduced snacking frequency by 26.1% (
conclusionStephan's curve-based nutrition counseling effectively reduced sugar intake and, to a lesser extent, snacking frequency. These findings support incorporating dietary education into routine dental care.
