Liver disease included chronic hepatitis B and nonalcoholic fatty liver disease. #Cancers involved the lung (n = 1), breast (n = 1), and colon (n = 1) in the COVID-19 group while for the non-COVID-19 group, lung (n = 3) and liver cancer (n = 1) were present. ξOxygen saturation < 95%. Data are expressed as mean ± standard deviation, median (Q1-Q3), or number (percent). The group comparison was performed by Student’s t-test, Mann–Whitney’s U test, or chi-square test. ALT: alanine aminotransferase; AST: aspartate aminotransferase; BMI: body mass index; CHD: coronary heart disease; CI: confidence interval; CK: creatine kinase; CKD: chronic kidney disease; COPD: chronic obstructive pulmonary disease; CRP: C-reactive protein; CT: computed tomography; diabetes: diabetes mellitus requiring treatment; GGO: ground-glass opacity; LDH: lactate dehydrogenase; OR : odds ratio.
