Drug survival analysis of dupilumab and associated predictors in patients with atopic dermatitis in South Korea: single-center, retrospective study.
Article in Scientific reports, 2024. 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
Dupilumab is a biologic medication that is used for the treatment of moderate-to-severe atopic dermatitis (AD). Long-term data on dupilumab drug survival in Asia patients with AD are limited. A single-center, retrospective study was performed to assess drug survival between March 2019 and March 2023. Drug survival and associated characteristics were analyzed using Kaplan-Meier survival curves and multivariate Cox regression analysis, respectively. A total of 124 patients with AD (Mean age [standard deviation], 26.0 [8.6] years) with a 4 years-overall dupilumab drug survival rate of 87.9%, were included in this study. Characteristics associated with shorter drug survival were the low eczema area and severity index (EASI) scores at baseline (hazard ratio [HR] 0.84; 95% confidence interval [CI] 0.75-0.94, p-value = 0.003) and non-insurance coverage of dupilumab (HR 11.87; 95% CI 3.28-42.99, p-value = 0.001). This retrospective study demonstrated good overall 4-year dupilumab survival (87.6%) in South Korea. Patients with low baseline EASI scores and those who did not have insurance for dupilumab treatment discontinued the therapy frequently. To the best of our knowledge, this is the first long-term dupilumab drug survival study conducted in Asia with predictors.
