Analysis of 1255 COVID-19 patients in Wuhan Tongji Hospital finding 0.61% with systemic autoimmune diseases, much lower than authors expected (3%-10%). Authors hypothesise that protective factors, such as CQ/HCQ use, reduce hospitalization.
This study is excluded in the after exclusion results of meta analysis: significant unadjusted confounding possible.

What is already known about this subject? ► On 12 March, WHO declared COVID-19 could be characterised as a pandemic. Till 22 April, more than 2.5 million cases of COVID-19 have been reported worldwide. ► Increasing data about COVID-19 based on the general population has been reported. However, little published works were found about COVID-19 in disease-specific groups. What does this study add? ► We analysed the epidemiology of 1255 inpatients with COVID-19 who were admitted to Wuhan Tongji Hospital. Additional 17 patients with systemic autoimmune diseases (AIDs) were further screened, the demographic characteristics, epidemiological history, comorbidities, clinical symptoms or signs on admission, chest CT findings, laboratory results on admission, therapies that were prescribed for COVID-19 as well as AIDs, and clinical outcomes were reported. The detailed information of patients with systemic AIDs was investigated.
