We retrospectively reviewed the records of the cirrhosis patients admitted between January 2018 and April 2021 to select the cases and controls. Cirrhosis patients discharged after recovery from COVID-19 were selected as cases. Controls were selected from those who were admitted with cirrhosis-related complications without COVID-19. RT-PCR testing was available only for the controls admitted after the onset of the COVID-19 pandemic. The cases and controls were subjected to propensity score matching.
