Impact of oral care knowledge on oral health behaviors among older residents of Nanjing: a cross-sectional study.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo explore the impact of oral care knowledge on the oral health behaviors of the older person.
methodsA convenience sampling method was used to distribute online questionnaires to older adults aged 60 and above in Nanjing. A total of 314 questionnaires were distributed, and 294 valid questionnaires were collected, with an effective response rate of 93.63%.
resultsThe awareness of oral health knowledge among the older adults aged 60 and above was inadequate (11.56%), with low awareness rates regarding, and knowledge related to oral cosmetology. The results from the adjusted Poisson regression analysis showed that monthly income ( p = 0.001), education level (p = 0.006), brushing frequency (p < 0.001), toothbrush replacement (p = 0.008), mouth rinse after meals (p < 0.001), dental plaque (p < 0.001), sugar causes dental caries (p < 0.001), treatment time (p < 0.001), gum bleeding (p = 0.001), causes of bleeding (p = 0.001), the hazards of tooth loss (p < 0.001), and the three major diseases (p = 0.011) remained the main influencing factors for oral health behaviors.
conclusionOral health knowledge among the older adults in Nanjing is currently insufficient and represents a key modifiable factor influencing behavior. Targeted health promotion should prioritize populations with lower socioeconomic status and address critical knowledge gaps to improve oral health practices.
