Treatment patterns of biologic disease-modifying anti-rheumatic drugs in juvenile idiopathic arthritis: a population-based study in Korea.

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
Objective: Juvenile idiopathic arthritis (JIA) is the most common chronic arthritis in children, with an unknown cause and prolonged disease course. Biologic disease-modifying anti-rheumatic drugs (bDMARDs) have improved outcomes in severe or refractory cases, but challenges remain due to disease heterogeneity and long-term management needs. Understanding treatment patterns of novel therapies is essential for optimizing care. This study aimed to investigate bDMARD treatment patterns in JIA patients using a real-world database. Methods: A retrospective analysis was conducted using Health Insurance Review and Assessment (HIRA) national claims data from 2007 to 2019. JIA patients were classified into bDMARDs and non-bDMARDs groups, with treatment patterns compared. Results: Among 1,728 JIA patients, 31.3% (n=541) received bDMARDs, with 15.5% (n=84) discontinuing treatment. The median time from diagnosis to first bDMARD was 36.7 (9.7~58.1) months, with a median treatment duration of 28.1 (11.5~54.4) months and follow-up of 24.3 (7.7~43.7) months post-discontinuation. In the non-bDMARDs group (68.7%, n=1,187), 68.7% (n=815) used conventional synthetic DMARDs (csDMARDs), with a 46.6% (n=380) discontinuation rate. Methotrexate, sulfasalazine, and hydroxychloroquine were the most prescribed csDMARDs. Etanercept (69.7%) was the most common first bDMARD, followed by adalimumab (19.0%) and tocilizumab (7.6%), with 14.8% switching to a second biologic. Discontinuation rates of csDMARDs were higher in the non-bDMARDs group (p<0.001). Conclusion: This is the first comprehensive study profiling the treatment patterns of Korean patients with JIA using population-based claims data. The findings enhance understanding of real-world treatment trends, aiding clinical decision-making.
