Analysis based on COVID-19 Global Rheumatology Alliance physician-reported registry showed that anti-TNF agents were associated with a lower risk of hospitalization (aOR 0.40, 95% CI 0.19-0.81) (20) and did not alter the mortality(aOR 0.85, 95%CI 0.52-1.36) (21), after controlling factors of age, sex, diagnosis, comorbidities and concomitant medication (20). Here, TNF is linked to COVID-19.
