Association Between a Body Shape Index and Body Roundness Index with Prevalence of Psoriasis: A Cross-Sectional Population-Based Study.

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
Background: Previous studies have suggested an intimate association between obesity and psoriasis. This study aimed to evaluate and compare the association between traditional and novel obesity biomarkers - waist circumference (WC), body mass index (BMI), a body shape index (ABSI), and body roundness index (BRI) - and the risk of psoriasis. Methods: This cross-sectional study utilized data from the 2003-2006 and 2011-2014 National Health and Nutrition Examination Survey. The association between obesity biomarkers and psoriasis risk was evaluated using multivariate logistic regression and smoothed curve fitting. The diagnostic performance of various biomarkers for identifying psoriasis were calculated and compared using receiver-operating characteristic curves. Results: Overall, 12,406 participants without psoriasis, 287 with mild psoriasis, and 68 with moderate-severe psoriasis, were included. Compared to the lowest quartile of WC, BMI, and BRI, higher quartiles were associated with significantly higher risks of psoriasis (all P for trend < 0.05). The area under the curve for identifying psoriasis was highest for BRI, which was comparable to WC (0.581 vs 0.575, P=0.34) but significantly higher than that of ABSI (0.581 vs 0.546, P=0.04) and BMI (0.581 vs 0.569, P=0.007). The association between BRI and psoriasis risk was not influenced by participant's age, sex, smoking status, physical activity, hypertension and diabetes status. Conclusion: BRI is positively associated with risk of psoriasis and outperforms BMI and ABSI in identifying psoriasis. Given the cross-sectional design of this study, future research employing prospectively designed longitudinal studies is necessary to validate our findings.
