The Nutritional Pathway Between Tooth Loss and Healthy Ageing: A Longitudinal Study of Older American Adults.
Article in Nutrients, 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
objectivesThis study examines the mediating role of nutritional intake in the relationship between tooth loss and healthy ageing in older American adults.
methodsA secondary data analysis was conducted using the Health and Retirement Study (HRS), a longitudinal survey of American older adults aged 50 years and over. Data from six waves from 2006 to 2016 were used. Nutritional intake was assessed in 2013 using ten essential nutrients, categorised as adequate or inadequate based on national dietary recommendations. Healthy ageing was an aggregate variable composed of freedom from cognitive impairment, freedom from disability, and high physical functioning. Tooth loss was measured as a dichotomous variable (edentate/dentate). Structural equation modelling was used to assess the associations between tooth loss in 2012, nutrition in 2013, and healthy ageing in 2016, accounting for demographic/socioeconomic factors and behaviours.
resultsA total of 3665 participants were included on the analysis. A significant association was found between being dentate in 2012 and nutritional intake in 2013 (coefficient 0.63: 95% CI: 0.62, 0.54,
conclusionsThe findings underscore the complex interplay of nutrition, socioeconomic status, health behaviours, and oral health in predicting healthy ageing trajectories. This study highlights the importance of oral health to maintaining adequate nutritional intake, which in turn promotes healthy ageing.
