Association between weight-adjusted waist index and depression in adults with diabetes: a cross-sectional study.
Article in BMC psychiatry, 2025. 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
backgroundThe weight-adjusted waist index (WWI) is a new way to measure central obesity, reflecting body fat distribution more effectively. The association between WWI and depression in individuals with diabetes is still not well understood. This study explores this association in diabetic patients.
methodsThis study involved adult participants diagnosed with diabetes mellitus in NHANES 2009–2018. We explored the association between WWI and depression through multivariate logistic regression analysis, subgroup analyses, interaction tests, and smoothed curve-fitting methods.
resultsIn Model 3, this study found a significant positive association between WWI and depression among patients with diabetes (OR = 1.38, 95% CI: 1.17–1.63). In the smoothed curve fitting analysis, a nonlinear relationship between WWI and depression was observed, with an inflection point at 12.31. Subgroup analysis indicated that this association was influenced by the poverty income ratio (PIR), with a stronger association observed among diabetic patients with PIR ≥ 1, < 3, and PIR ≥ 3.
conclusionsAmong patients with diabetes, WWI was significantly positively associated with the prevalence of depression. This association was more pronounced among diabetic patients with PIR ≥ 1, < 3, and PIR ≥ 3. These findings suggest that WWI may be a relevant factor for physicians to consider when assessing depressive symptoms in patients with diabetes.
