Association between multimorbidity and having less than 20 natural teeth among Chinese older adults: a cross-sectional study.

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
Understanding the impact of multimorbidity on having less than 20 natural teeth is crucial for safeguarding the oral health of older adults with multimorbidity. This study aimed to analyze the association between multimorbidity and having less than 20 natural teeth in older Chinese adults. The data for this analysis were obtained from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), which covers 23 provinces, municipalities, and autonomous regions throughout China. The survey includes information on dental health (such as dentition status), a variety of chronic conditions, and other sociological characteristics of older adults in China. Having less than 20 natural teeth was used as the dependent variable, with multimorbidity as the independent variable. A multivariable logistic regression model was applied to estimate the association between multimorbidity and having less than 20 natural teeth. A total of 3,640 older adults were included in the study, of whom 58.27% (2121) were identified as having less than 20 natural teeth. The results indicated that factors such as age, education level, exercise, ability to perform daily activities, frequency of brushing teeth, and BMI are associated with having less than 20 natural teeth. Additionally, compared with those without chronic disease, the odds ratio (OR) of having less than 20 natural teeth was 1.32 (95% CI: 1.10, 1.57) for older adults with only one chronic disease, and the OR for those with two or more chronic diseases was 1.418 (95% CI: 1.06, 1.89). This study highlights the importance of monitoring the oral health of older adults with multimorbidity and identifies an association between multimorbidity and having less than 20 natural teeth. Oral health care institutions should implement measures to support the development of more comprehensive public health policies.
