Final Analysis of COVID-19 Patients With Inflammatory Bowel Disease in Japan (J-COSMOS): A Multicenter Registry Cohort Study.

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 and Aims: Japan has experienced 8 waves of the coronavirus disease 2019 (COVID-19) outbreak over the past 3 years, resulting in an increasing number of deaths and incidence of severe infections. This study aimed to analyze the data from the Japanese inflammatory bowel disease (IBD) patients with COVID-19 registry (J-COSMOS) up to the eighth wave to investigate the clinical course of IBD patients with COVID-19 and factors contributing to disease severity. Methods: In this multicenter, observational, cohort study, we analyzed a cohort of 1308 IBD patients diagnosed with COVID-19, enrolled across 77 participating facilities in the J-COSMOS registry from June 2020 to December 2022. Data on age, sex, IBD (classification, treatment, and activity), and COVID-19 (symptoms, severity, and treatment) were analyzed. Results: The majority of patients (76%) were in clinical remission. According to the World Health Organization classification of COVID-19 severity, 98.4% of IBD patients had nonsevere disease, while 1.6% of patients had severe or critical disease. COVID-19 did not affect disease activity in most IBD patients. Stepwise logistic regression analysis revealed that high body mass index, and cerebrovascular disease were risk factors for severe COVID-19. Corticosteroids could affect COVID-19 severity, whereas anti-tumor necrosis factor α antibodies and thiopurines were associated with a reduced risk of severe COVID-19. No deaths were observed among IBD patients with COVID-19 registered in this cohort. Conclusion: The impact of COVID-19 on IBD disease activity and factors associated with COVID-19 severity were consistent with findings of previous reports. No deaths in Japanese patients with IBD were observed.
