The Clinical Characteristics of Psoriatic Arthritis: A Cross-Sectional Study Based on the Psoriatic Arthritis Cohort of West China Hospital.
Article in Rheumatology and therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionThis study aims to describe the demographic, clinical, laboratory, and ultrasonic characteristics of patients with psoriatic arthritis (PsA) in the Psoriatic Arthritis cohort of West China Hospital.
methodsIn this cross-sectional study, we included patients diagnosed with PsA according to the Classification Criteria for Psoriatic Arthritis, collected their demographic information, medical histories, and treatments, evaluated all domains (skin and nail lesions, tenderness, swelling, enthesitis, dactylitis, and axial arthritis) related to PsA, and then performed descriptive statistical analyses of all data.
resultsA total of 275 patients with PsA were included in this study. The ratio of male to female patients was 2.16:1. Skin lesions preceded arthritis in 86.5% of these patients with PsA with a mean interval of 10.1 years. The metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints of fingers, and sacroiliac joints are the most commonly involved sites of tenderness, swelling, and the spine, respectively. Among all comorbidities, fatty liver has the highest incidence with 33.1%. Finally, we noted that the mean disease duration of PsA was 4.2 years, suggesting a delay in the diagnosis of PsA.
conclusionOur study proposes that the prevalent population of PsA are male patients with psoriasis over 40 years of age who have a long disease course. For patients with PsA, MCP, PIP joints of fingers, and sacroiliac joints are the most frequently affected anatomical sites. With respect to comorbidities, the association between PsA and fatty liver and the underlying molecular mechanisms are worthy of further exploration.
