Relationship between dietary inflammation index and progression of vitiligo.
Article in Nutrition journal, 2026. 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
backgroundVitiligo is a melanocyte-destructive depigmenting disease linked to immune inflammation, with diet potentially mediating inflammatory processes via immune dysregulation. However, the specific role of diet in vitiligo pathogenesis remains understudied.
objectiveTo investigate the association between Dietary Inflammatory Index (DII) and vitiligo onset or progression, for developing novel prevention strategies.
methodsA case-control study included 80 progressive vitiligo patients (2024 Jan-Mar, Shuguang Hospital) and 80 sex/age-matched controls. Dietary intake was assessed via semi-quantitative food frequency questionnaire (SQFFQ), with DII scores calculated. Logistic regression and Spearman analysis evaluated DII-vitiligo associations.
resultsCases had significantly higher DII levels (Z=-2.054, P = 0.042). Each 1-unit DII increase correlated with a 23% higher vitiligo risk (OR = 1.23, 95% CI: 1.005-1.504, P = 0.044), with a positive Spearman correlation (r = 0.161, P < 0.05).
conclusionPro-inflammatory diets may increase the risk of vitiligo occurrence and development. Adjusting the dietary structure may help prevent and control the disease. This study provides a new basis for dietary interventions in vitiligo. LIMITATIONS: Limitations include small sample size and reliance on global DII norms (lacking Chinese standards), warranting multi-center, large-scale studies.
