Epidemiology and comorbidity of juvenile idiopathic arthritis in Poland- a nationwide study.
Article in Pediatric rheumatology online journal, 2025. 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
backgroundDiagnostic pathways for patients with juvenile idiopathic arthritis (JIA) have gradually improved over time. Provider practice has also shifted towards goal-oriented treatment with disease-modifying drugs (DMARDs) that together may have changed the epidemiologic landscape of JIA.
methodsPublic healthcare utilization records from the National Health Fund (NHF) were screened between 2010 and 2022. For individuals aged < 16 years, we utilized a narrow JIA case definition combining repeat ICD-10 encoding with DMARDs prescription based on ATC codes.
resultsIn 2022, we identified 1,625 incident and 29,758 prevalent JIA cases (< 16 years), which corresponds to incidence (IRs) and prevalence rates of 4.30 and 78.80 per 100,000 persons of the general population. For the pediatric population, annual IRs for JIA (< 16 years) ranged between 24.0 (95% CI 22.8, 25.2) and 38.7 (95% CI 37.2-40.3) per 100,000. Greater susceptibility among females was also consistently observed with the annual IR ratio ranging between 1.16 and 1.53. The most common concurrent disorders based on medical care services were allergic rhinitis (N = 5,200, 17.5%), bronchial asthma (N = 3,661, 12.3%) and chronic tonsillitis/pharyngitis (N = 3641, 12.2%). Analysis of 214,285 outpatient care visits revealed a median (IQR, range) annual healthcare cost of 37.8€ (35.8-47.4€, 30.3-86.1€) per JIA patient.
conclusionsThis comprehensive, nationwide study provides a contemporary estimate of JIA burden in Poland. Our findings indicate that both the occurrence of new cases and overall burden of JIA in the past ten years align with the lower end of projected figures for our geographical area, especially when compared with Scandinavian nations.
