Oral Factors Associated with Swallowing Function in Independent Elders.
Article in Oral health & preventive dentistry, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study clarified the oral factors related to swallowing function using the results of dental check-ups among community-dwelling independent elders. MATERIALS AND
methodsData on oral and medical health check-ups from 4,676 participants aged 75 and 80 years were analysed. Swallowing function was evaluated using the repetitive saliva swallowing test (RSST), which assesses the ability to swallow saliva. Swallowing three or more times during a 30 s period was recorded as normal, while swallowing twice or less in 30 s was considered to indicate swallowing difficulty. Multivariate logistic regression analyses were performed to examine the relationship between oral factors and swallowing function.
resultsIn all participants, the odds ratio (OR) for swallowing difficulty was 3.42 (95% confidence interval (CI): 1.78-6.55) and 6.68 (95% CI: 1.97-22.64) among those who had 10-19 teeth without dentures and those who had 0-9 teeth without dentures, respectively, compared to individuals with ≥ 20 teeth without dentures. Those with moderate or severe dry mouth had a statistically significantly higher OR (8.01, 95% CI: 4.84-13.27) for swallowing difficulty than those without dry mouth. Among dentate participants, in addition to statistically significant variables in the analysis among all participants, those with abundant dental plaque showed a significantly higher OR (2.58, 95% CI: 1.54-4.32) for swallowing difficulty compared to those with no or slight dental plaque.
conclusionThese results suggest that oral factors such as having few teeth without dentures, dry mouth, and poor oral hygiene are related to swallowing function in elders.
