The association of food insecurity with tooth decay and periodontitis among middle-aged and older adults in the United States and Korea.
Article in Gerodontology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionFood insecurity is an important social determinant of health, but there is limited understanding of its relationship with adult oral health. This study examined the associations between food insecurity and dental diseases (caries and periodontitis) among middle-aged and older adults in the United States and South Korea.
methodsThis study focused on middle-aged (40-59 years) and older adults (>59 years) who participated in the 2011-2016 US National Health and Nutrition Examination Surveys (NHANES) or the 2013-2015 South Korean NHANES. The exposure was food insecurity severity (food secure/early-stage food insecurity/middle-stage or severe food insecurity) assessed using the 18-item US Household Food Security Survey Module. The two outcomes were any untreated tooth decay and periodontitis measured using the Modified Community Periodontal Index of Treatment Needs. Covariate-adjusted odds ratios (OR) with 95% confidence intervals (CI) were generated using multivariable logistic regression models.
resultsMiddle or severe food insecurity was associated with significantly higher odds of having untreated tooth decay than no food insecurity, but only among middle-aged adults in the United States (OR: 1.4, 95% CI 1.2, 1.9; P = .037) and Korea (OR = 1.8; 95% CI:1.0, 3.2; P = .036) and older adults in the United States (OR: 2.6, 95% CI 1.7, 4.0; P < .001). The associations between food insecurity and periodontitis were inconsistent across age group and country.
conclusionDiffering cultural norms and access to dental services in the United States and South Korea may influence the relationship between food insecurity and oral health. Future research should explore how addressing food insecurity could help to promote the oral health of middle-aged and older adults in diverse sociocultural contexts.
