The Omicron cohort was designed prospectively, and the RV cohort was retrospective. Survival outcomes, medical resources, and major complications were compared. Risk factors associated with peri-operative mortality were investigated using regression analysis. We enrolled 649 paediatric liver transplantation patients, including 28 Omicron and 61 RV infections.
