The impact of physical activity on the prevalence of edentulism: an analysis of the relationships between active lifestyle and dental health.
Article in BMC public health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundEdentulism is considered the ultimate sign of oral health disease burden. It is a common and frequent clinical disease, mostly seen in the elderly, which has been reported to be closely associated with many diseases. While physical activity is known to benefit many chronic diseases, the relationship between the volume of physical activity and edentulism remains unclear. MATERIALS AND
methodsThe CHARLS provided the data for this study. A total of 6,480 participants were enrolled in this study, of whom 46.02% were male and 53.98% were female. The edentulism was defined according to self-report and physical activity volume can be represented by metabolic equivalents. Multiple logistic regression, smooth curve fitting, threshold effects analysis, and Cox regression models were used to explore the relationship between physical activity volume and edentulism.
resultsIn the fully adjusted model, physically active participants had a 24% lower risk of edentulism compared to those who were physically inactive. Then, we subdivided participants with adequate physical activity into four levels: 600 ≤ PAV < 1200; 1200 ≤ PAV < 1800; 1800 ≤ PAV < 3000; and PAV ≥ 3000. We found that the risk of developing edentulism was lowest and statistically significant at the level of 1,800-3,000 MET-minutes/week physical activity volume (OR = 0.41; 95% CI, 0.24-0.69, p < 0.001). A U-shaped relationship between physical activity volume and edentulism with an inflection point of 2514 (MET-minutes/week) was observed. The results of the longitudinal study also confirm the benefits of physical activity volume with edentulism, participants with adequate physical activity volume had a 21% lower risk of developing edentulism than participants with inadequate physical activity volume (HR = 0.79; 95% CI, 0.67-0.94, p = 0.008).
conclusionsThis study reveals a U-shaped relationship between physical activity volume and edentulism. Physical activity reduces the risk of developing edentulism in middle-aged and older populations, but it is important to control the appropriate volume of physical activity.
