1 · What the graph read from it

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.

2 · The registry

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

backgroundThe specific role of visceral adiposity in dental caries risk remains underexplored.

objectiveThis study investigated the association between visceral adiposity index (VAI) and dental caries outcomes in a nationally representative adult population.

methodsThis cross-sectional study analyzed NHANES 2011–2018 data from 7,048 adults aged ≥ 20 years with complete VAI and dental information. VAI was calculated using gender-specific formulas incorporating waist circumference, BMI, triglycerides, and HDL-cholesterol. Untreated dental caries was defined as presence of active decay, while dental caries experience included decayed, missing, or filled teeth. Multivariable logistic regression models assessed associations, adjusting for demographic, socioeconomic, and clinical factors.

resultsSignificant non-linear associations were observed between VAI and both dental caries outcomes (P for non-linearity < 0.001). In fully adjusted models, each unit increase in VAI was associated with 7.4% higher odds of untreated dental caries (OR = 1.074, 95% CI: 1.032–1.118, P < 0.001) and 9.4% higher odds of dental caries experience (OR = 1.094, 95% CI: 1.011–1.183, P = 0.026). Quartile analysis revealed a dose–response relationship for untreated dental caries, with the highest VAI quartile showing 65.1% higher odds compared to the lowest quartile (OR = 1.651, 95% CI: 1.324–2.059, P < 0.001). Significant effect modifications were observed by education level (P for interaction = 0.042) and hyperlipidemia status (P for interaction = 0.009).

conclusionVisceral adiposity, as measured by VAI, is independently associated with increased dental caries risk, representing a potential modifiable risk factor warranting clinical attention.
