Obesity mediates the association between psoriasis and diabetes incidence: a population-based study.
Article in Diabetology & metabolic syndrome, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
introductionThe aim of this study was to explore the association between psoriasis and diabetes and to assess the potential moderating role of obesity in this relationship.
methodsThe study involving data from 21,835 NHANES participants during 2003-2006 and 2009-2014. The analysis included body mass index (BMI), as well as information about psoriasis and diabetes obtained from questionnaires. The study employed weighted logistic regression to examine the association between psoriasis and diabetes. The nonlinear relationship between obesity, diabetes, and psoriasis was explored through smooth curve fitting, stratified by age and gender. In addition, the authors conducted mediation analysis, which suggested that obesity partially mediated the association between psoriasis and diabetes prevalence.
resultsAfter adjusting for relevant variables, we found that individuals with psoriasis had a significantly higher incidence of diabetes (OR = 1.48, 95% CI = 1.16-1.90, P = 0.002). A positive relationship was identified between BMI levels and diabetes occurrence among individuals with psoriasis, with a significant difference observed between the highest (Q4) and lowest (Q1) BMI quartiles (P < 0.05). Further analysis using smooth curve fitting demonstrated the consistent association between BMI and diabetes, which was also evident in psoriasis patients. Age-stratified analysis showed that diabetes was more prevalent among older adults compared to younger individuals at the same BMI levels. For psoriasis, an inflection point was noted in men where its prevalence began to decline as BMI exceeded a certain threshold. Similarly, in younger adults, psoriasis prevalence decreased above a specific BMI threshold. Additionally, mediation analysis indicated that obesity played a partial role in linking psoriasis and diabetes, accounting for approximately 22.91% of this association.
conclusionThe study found an association between psoriasis and diabetes. Additionally, the analysis suggested that obesity may partially contribute to this relationship, indicating it could play a role in linking the two conditions.
