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
Aims: The study aims to analyze the association pathways of factors related to oral health behaviors among older diabetic patients in Shanghai, China, using the COM-B model. Methods: A convenience sample of 358 older diabetic patients was enrolled between July 2025 and December 2025 from one tertiary hospital and a community health service center in Shanghai. Information was collected via a general information questionnaire, the Older Oral Health Knowledge, Belief and Behavior Questionnaire, the 14-item Health Literacy in Dentistry Scale, the Perceived Social Support Scale, the Geriatric Self-Efficacy for Oral Health Scale, and the 5-item Geriatric Depression Scale. Descriptive statistics, univariate analysis, correlation analysis, and path analysis were adopted to analyze the relevant factors and pathways of oral health behaviors. Results: The constructed structural equation model showed satisfactory goodness of fit (χ Conclusion: Capability factors, opportunity factors, and motivational factors are directly or indirectly associated with the oral health behaviors among older diabetic patients. This suggests that clinicians regularly conduct diabetes-related oral health education and cleaning skills training, encourage relatives to provide supervision, improve access to oral healthcare, and provide psychological counseling to improve patients' oral health behaviors in terms of capability, opportunity, and motivation.
