Association between dental caries and self-reported COPD prevalence in U.S. adults ages ≥ 60-year: a cross-sectional analysis of NHANES 2015-2020.

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
Background: Evidence on the association between dental caries and chronic obstructive pulmonary disease (COPD) risk in older adults is limited. Objective: This cross-sectional study aimed to explore the associations of coronal and root caries with self-reported COPD prevalence in this population. Design: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2015-2020. Coronal caries was measured by the decayed, missing and filled teeth (DMFT) index. Root caries was recorded as presence or absence. Weighted multivariable logistic regression models were applied to assess the associations of coronal caries and root caries with COPD. Results: A total of 3,972 eligible participants were included, with a weighted self-reported COPD prevalence of 13.68%. Per 1-unit increase in DMFT was associated with higher odds of COPD (OR = 1.04, 95%CI: 1.02-1.06, Conclusions: Coronal and root caries are independently associated with higher odds of self-reported COPD in U.S. older adults. However, given the cross-sectional design, causal inference cannot be established, and further prospective research is needed.
