Prevalence, severity, outcomes, and risk factors of COVID-19 in multiple sclerosis: An observational study in the Middle East.

A cross-sectional hospital records-based study was conducted to evaluate the prevalence, severity, outcomes, and identify demographic and clinical risk factors of coronavirus disease (COVID-19) in patients with MS. The study was conducted at multiple clinics in Oman, Kuwait, and the United Arab Emirates (UAE) from March 2020 to February 2021. The association of patient demographics, MS disease characteristics, and use of disease-modifying therapies with outcomes of COVID-19 illness were evaluated using odds ratio.
