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

The Weight-adjusted Waist Index (WWI) is a novel anthropometric indicator for assessing obesity. Given the well-established association between obesity and periodontitis, this cross-sectional clinical study aimed to investigate the relationship between WWI and severe periodontitis while evaluating its potential as a simple predictive marker for periodontitis. The study analyzed periodontal examination data and WWI measurements from participants in the 2009-2014 National Health and Nutrition Examination Survey (NHANES), employing weighted logistic regression, smoothed curve fitting, and subgroup analyses. Among the 10,307 eligible participants, results demonstrated a significant positive correlation between WWI and the prevalence of stage III/IV periodontitis. After comprehensive adjustment for all confounding factors, each 1-unit increase in WWI was associated with a 1.19-fold higher risk of stage III/IV periodontitis (OR = 1.19, 95% CI 1.06-1.32, P = 0.007977). Subgroup analysis revealed that this association showed statistically significant variation only in the hypertension subgroup, indicating that the WWI-severe periodontitis relationship is particularly applicable to non-hypertensive individuals. These findings confirm that WWI can serve as a novel obesity-based predictive indicator for severe periodontitis.
