Study characteristics

China

Retrospective cohort study

Medical records

140

patients with COVID-19

A total of 140 patients with COVID-19 were included in this study (one patient was excluded because of massive gastrointestinal hemorrhage). In the study population, 107 patients were assigned to a mild group (MG) and 33 patients were allocated to a severe group (SG). There was no significant difference in the male to female ratio between the two groups. The median age was 65.5 years (range, 23–96). The average age was significantly higher in the SG than in the MG (P<0.0001)
