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

backgroundPeriodontitis is a common chronic oral inflammatory disease with multiple etiologies. The relationship between Dietary Diversity Score (DDS) and periodontitis prevalence remains unclear.

objectiveTo elucidate the DDS-periodontitis prevalence association.

methodsLogistic regression evaluated the linkage between DDS and periodontitis. Restricted cubic spline (RCS) regression assessed non-linear linkage. Interaction tests identified effect-modifying factors. Weighted quantile sum (WQS) regression identified food categories influencing associations. Mediation analysis investigated the mediating roles of body roundness index (BRI) and red blood cell distribution width (RDW).

resultsIn the full-adjusted model, higher DDS was linked with lower periodontitis prevalence odds (odds ratio [OR]: 0.95; 95% confidence interval [CI]: 0.93-0.98; p < 0.001), with an evident dose-response relationship. RCS indicated no significant non-linear association between DDS and periodontitis (p-non- linear = 0.144). WQS showed balanced weight distribution of five main foods (all ~20%), indicating a dietary synergy effect. Subgroup analyses revealed significant interactions between DDS and periodontitis within subgroups of age, smoking, BMI, alcohol consumption, and osteoarthritis (p-interaction < 0.05). RDW (2.26%) and BRI (1.69%) partially mediated the linkage between DDS and the periodontitis prevalence.

conclusionHigher DDS is independently associated with reduced prevalence of periodontitis, driven by the synergistic contribution of multiple food categories. Optimizing dietary breadth is important in preventing periodontitis.
