Renal Implications of Psoriasis: Urinary Podocyte Markers and Disease Progression.
Article in Dermatology practical & conceptual, 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
introductionPsoriasis may lead to glomerular inflammatory damage and disruption of the podocyte barrier, allowing podocyte degradation products to leak into the urine.
objectivesWe aimed to analyze the concentrations of podocyte surface glycoprotein podocalyxin (PDX) and podocyte slit protein nephrin in spot urine samples from patients with mild, moderate, or severe psoriasis vulgaris.
methodsA total of 78 participants, including 58 patients diagnosed with mild, moderate, or severe psoriasis vulgaris and 20 healthy controls, were included in the study. Psoriasis was diagnosed based on the typical morphological characteristics of the lesions. Morning urine samples were used to evaluate urine PDX and nephrin levels. Albuminuria was evaluated by calculating the urine albumin-to-creatinine ratio (uACR).
resultsUrinary PDX and nephrin levels were significantly higher in the psoriasis group than in the control group. Urinary PDX and nephrin levels in the mild and moderate psoriasis groups were similar but higher than those in the control group and significantly higher in the severe psoriasis group than in the mild and moderate psoriasis groups. The microalbuminuria rates were similar between the psoriasis and control groups. A significant positive correlation was observed between urine PDX, nephrin, uACR, and SBP. After adjusting for age, BMI, and sex, urine PDX and nephrin levels were found to be independent risk factors for microalbuminuria.
conclusionThis study showed that podocyte damage in patients with psoriasis begins in the early stages of the disease and significantly increases in the severe stage of the disease.
