COVID-19 outcomes in patients with inflammatory rheumatic diseases: associations with disease subtypes, treatments, and vaccination status.
Observational study in Frontiers in public health, 2026. 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
Background: Patients with inflammatory rheumatic diseases (IRDs) may be at increased risk for adverse COVID-19 outcomes because of immune dysregulation, comorbidities, and immunomodulatory treatments. However, the effects of specific rheumatic disease subsets, treatment patterns, and vaccine types remain incompletely understood. Objective: To evaluate clinical characteristics and factors associated with COVID-19 infection and hospitalization among patients with IRDs. Methods: This retrospective observational cohort study included 1,024 adult patients with IRDs followed between March 2020 and January 2023. Demographic characteristics, rheumatic disease subtypes, treatments, vaccination status, COVID-19 infection, hospitalization, radiologic findings, and recovery duration were analyzed. Results: Among all patients, 347 (33.9%) developed COVID-19 infection. Patients with COVID-19 were younger than those without COVID-19 (49.1 ± 13.4 vs. 51.5 ± 14.5 years, Conclusion: Older age, pulmonary comorbidity, longer disease duration, and radiologic involvement were associated with COVID-19-related hospitalization in IRDs. In contrast, FMF, colchicine use, and BNT162b2 vaccination were associated with lower hospitalization rates.
