Continuous variables are expressed as the median and interquartile range (IQR = Q3 – Q1), and categorical variables are presented as numbers with percentages. Abbreviations: CT, computed tomography; DIC, disseminated intravascular coagulation; EGD, esophagogastroduodenoscopy; ETT + MV, endotracheal tube with mechanical ventilation; GI, gastrointestinal; ICU, intensive care unit. 1 Survival is expressed as the rate at the endpoint of the follow-up period (March 2021). The p-values were calculated using log-rank tests.
