Impact of dietary intervention and supplementation on the physiological profile of individuals with down syndrome.
Article in Scientific reports, 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
Down syndrome, or trisomy 21 (T21), is a genetic neurodevelopmental disorder (NDD) often associated with various health challenges. In this population, physiological alterations remain poorly recognized, including dysregulated interactions among systems that play important roles in maintaining homeostasis. Common challenges include nutritional deficiencies, impaired metabolic detoxification, a hypoxia-like state, and gut dysbiosis. This study investigates the impact of dietary interventions and nutrient supplementation on the physiological profiles of individuals with T21. Using a database from the “Integración Down” Institute in Mexico City, we analyzed a panel of 121 biochemical markers before and after a 10-month intervention period. The interventions comprised dietary restriction alone (D) and dietary restriction with nutrient supplementation (D + S), aimed at modifying the participants’ physiological profiles. Our findings demonstrate changes in several physiological markers following the interventions, mainly in response to D + S. In particular, we observed changes in dysbiosis markers related to bacterial and fungal overgrowth; the D + S protocol reduced biomarkers associated with fungal overgrowth. Biomarkers related to nutritional deficiency and a hypoxia-like state (described for T21) showed changes, especially in the D + S group. Increases in red‑blood‑cell indices and decreases in markers of metabolic pathway disruption suggest improved energy metabolism. This research highlights the potential of dietary interventions to ameliorate T21-associated comorbidities and improve overall health outcomes in this population. Further research is needed to explore the long-term effects and optimal strategies for personalized nutritional management in individuals with T21.
