Edentulism associates with worse cognitive performance in community-dwelling elders in rural Ecuador: results of the Atahualpa project.
Article in Journal of community health, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03693027 (Evaluation of a Daily Oral Care Lozenge on Oral Health and Quality of Life in Older Adults), which is not on this map. Cited by 20 papers, 3 of them syntheses that pooled it.
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.

Abstract
Studies in industrialized nations suggest that severe edentulism correlates with cognitive impairment, but there is little information on this association in underserved populations. We conducted a community-based study to assess whether edentulism associates with cognitive impairment in elders living in rural Ecuador. Atahualpa residents aged ≥60 years were identified during a door-to-door census and evaluated using the Montreal Cognitive Assessment (MoCA). Persons were classified into two groups according to whether they have severe edentulism (<10 remaining teeth) or not. In addition, a questionnaire allowed self-rating of oral health. A total of 274 persons (mean age 69.6 ± 7.7 years; 59% women) were included. Persons with <10 remaining teeth (n = 116) have significantly lower MoCA scores than those with ≥10 teeth (n =158), after adjusting for demographics, cardiovascular risk factors, depression and dementia (β = -1.06, p = 0.03). Self-rated poor oral health was more prevalent among persons with <10 teeth (p < 0.0001), but did not correlate with MoCA scores (good vs. poor, β = -0.89, p = 0.89). Severe edentulism is associated with poor cognitive performance in elders living in rural Ecuador. Public health campaigns directed to improve oral health may facilitate early recognition of persons with cognitive impairment in underserved populations.
