Association between dietary diversity and healthy aging: a systematic review.
Synthesis in BMC nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectiveThe proportion of older people has been enhanced in the past half-century around the world, consequently leading to the increasing overall prevalence of age-related health conditions. The present study aims to summarize the current evidence regarding the association between dietary diversity (DD) and the components of healthy aging.
methodsThe databases, including Scopus, PubMed, Web of Science, and Google Scholar, were searched using relevant keywords and without date restrictions up to November 2023. All original articles written in English evaluating the association between DD and healthy aging components were eligible for this systematic review.
resultsTotally, 2728 records were obtained in electronic search databases after removing duplicates and irrelevant studies based on the title and abstract; the full text of the 64 articles was critically screened, and 32 cross-sectional studies and 17 cohort studies were included in this review. Except for two cases, all of these studies (95.9%) reported that high DD was associated with lower cognitive and physical frailties, low sleep disturbance and mental disorders, and good nutritional status among the elderly population.
conclusionFindings suggest higher DD may contribute to healthy aging through improved nutrient intake and reduced risk of age-related diseases, but heterogeneity in study designs limits conclusive evidence. Enhancing healthy dietary behaviors for older people is suggested to increase their awareness and consequently DD. Further research is needed to confirm these results and the causal relationship.
