The clinical risk and post-COVID-19 sequelae in patients with myasthenia gravis: a retrospective observational study.
Article in Frontiers in neurology, 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
Background: There are indeed several studies addressing the severity of Coronavirus disease 2019 (COVID-19) infection in myasthenia gravis (MG) patients. However, data on post-COVID-19 sequelae in MG patients remain limited. To address this gap, we collected clinical data on the condition and prognosis of MG patients with COVID-19 infection, aiming to investigate factors influencing both the severity of the infection and the occurrence of post-COVID-19 sequelae at 1 and 12 months after recovery. Method: This was a retrospective analysis of 150 MG patients with COVID-19 infection from November 1, 2022 to March 1, 2023 at the First Affiliated Hospital of Guangzhou University of Chinese Medicine, including patient demographics, clinical characteristics, and post-COVID-19 sequelae. Multivariable binary logistic and linear regression models were employed to ascertain the variables influencing the severity. The evolution of the post-COVID-19 sequelae was analyzed using McNemar's test. Result: In 150 MG patients, 128 (85.3%) patients were presented with COVID-19 infection, and 23 (18%) patients were hospitalized. The severity was associated with the daily corticosteroid dose (OR = 1.08, Conclusion: Compared to normal patients, MG patients are prone to developing severe COVID-19 infection, which is associated with the daily corticosteroid dose and the frequency of myasthenia crises pre-COVID-19. Additionally, they are prone to experiencing post-COVID-19 sequelae, including insomnia, myalgia, dizziness, cough, expectoration, and sore throat, at 12 months after recovery.
