Severe COVID-19 in Patients with Immune-Mediated Rheumatic Disorders: A Case-Control Study.
Article in Open access rheumatology : research and reviews, 2025. 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
Purpose: To assess the impact of severe COVID-19 in patients with immune-mediated rheumatic diseases (im-RD) and compare their morbidity, mortality, hospitalization issues, post-COVID-19 sequelae, and the financial burden of COVID-19 with those of patients without im-RD. Patients and Methods: We conducted a retrospective case-control study that included 132 consecutive patients with im-RD who visited the Rheumatology Department of a public hospital in the Emirate of Dubai and were hospitalized for COVID-19 infection between March 1st, 2020, and December 31st, 2021, (cases). We included 264 and 132 age- and sex-matched patients without im-RD in matched-I and matched-II control groups, respectively. The median age of patients and controls was 48.5 years, and 74.2% were female. Patients with im-RD were paired with an unforced nearest neighbor match using a caliper width of 0.2 standard deviations of the matched-II control group's propensity score. We compared the relative risk of death, disease progress, use of medical resources, and financial impact of COVID-19 between patients and controls. Results: Patients with im-RD had higher mortality rates than the matched-I (odds ratio, OR: 11.2, p < 0.000) and matched-II (OR: 16.8, p < 0.006) control groups. The overall complication rate was also significantly higher in patients with im-RD than in matched-I (OR = 2.9, p < 0.000) and matched-II (OR = 2.8, P < 0.0001) control groups. Lastly, patients with im-RD required more frequent visits to the clinic, a longer recovery time following hospital discharge, and increased healthcare costs compared to the control groups. Conclusion: COVID-19 infection in patients with im-RD is associated with increased morbidity and mortality, exerting a significant burden on the healthcare system.
