Association Between Serum Vitamin D Levels and Periodontal Conditions According to Sleep Duration Using Data from Korea National Health and Nutrition Examination Survey.
Article in Oral health & preventive dentistry, 2024. 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
purposeThis study aimed to investigate the association between vitamin D levels and periodontitis according to sleep duration in a representative sample of Korean adults. MATERIALS AND
methodsA total of 3535 subjects who participated in the sixth (2013-2014) Korea National Health and Nutrition Examination Survey were examined. Vitamin D deficiency was defined as a 25-hydroxyvitamin D serum concentration of 20 ng/ml. Periodontal status was assessed with the community periodontal index (CPI). A high CPI was defined as a score ≥ 3. Multivariable logistic regression analyses were adjusted for sociodemographic variables, oral and general health behaviors, and systemic health status. All analyses used a complex sampling design, and a subgroup analysis was performed to determine estimates following stratification for sleep duration (≤ 5, 6, 7-8, and ≥ 9 h per day).
resultsMultivariable regression analysis indicated that among participants who slept for ≥ 9 h per day, those with vitamin D deficiency were 5.51 times (95% confidence interval = 2.04-14.89) more likely to have periodontitis than those with sufficient vitamin D levels. This association was not statistically significant in the other sleep duration groups.
conclusionThe findings of this study indicate that people with vitamin D deficiency who sleep 9 h or longer may also be statistically significantly more likely to have periodontitis.
