Factors Affecting Treatment Persistence in Japanese Patients with Psoriasis Prescribed Biologics: A Real-World Study Using an Insurance Claim Database.
Article in Dermatology and therapy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionPoor persistence to biologics can result in suboptimal health outcomes and increased economic burden for chronic conditions, including psoriasis (PsO). In Japan, studies evaluating factors responsible for biologic treatment persistence in patients with PsO are limited. We assessed biologic treatment persistence (median treatment duration and overall treatment survival) and associated factors in patients with PsO in a real-world setting.
methodsThis retrospective analysis of insurance claims records from the Japan Medical Data Center (JMDC) database included patients with PsO [International Classification of Diseases (ICD) code: L40.x] ≥ 18 years of age who had received biologic treatment. Treatment persistence was analyzed using data from 2016 to 2020 by biologic class and by individual biologics (infliximab, adalimumab, ustekinumab, guselkumab, secukinumab, ixekizumab, and brodalumab) in bio-naïve (who initiate first biologic at index) and bio-experienced patients. Kaplan-Meier survival (treatment persistence), and multivariate Cox proportional hazard regression (predictive factors) analyses were used.
resultsOverall, 1528 patients with PsO were included (mean age 47.4 years). Infliximab had the longest median treatment duration (33.6 months), while brodalumab had the shortest (9.7 months) among biologics evaluated. Of the biologics evaluated, 1-year treatment survival was highest with guselkumab (83%), and lowest with brodalumab (45%). Bio-experienced patients showed slightly longer median treatment duration than bio-naïve patients (22.8 versus 18.1 months). Factors predictive of treatment persistence were sex [male; hazard ratio (HR) 0.84, p = 0.016] and specific PsO diagnostic codes, such as L40.0 (PsO vulgaris; HR 0.69; p = 0.006), L40.1 (generalized pustular PsO; HR 0.75; p = 0.034), and L40.9 (PsO unspecified; HR 0.72; p = 0.001). Meanwhile, age and Charlson Comorbidity Index score were significantly associated with adalimumab and infliximab treatment persistence, respectively.
conclusionAmong biologics evaluated, infliximab had the longest median treatment duration, and guselkumab had the highest 1-year treatment survival. Sex and specific PsO diagnostic codes influenced overall treatment persistence. These findings could inform long-term treatment plans for PsO in real-world clinical settings.
