Statistical Analysis
Continuous data are presented as mean (± standard deviation) for normally distributed variables or median (interquartile range (IQR)) for non-normally distributed variables. Categorical data are displayed as number (percentage). Preoperative baseline characteristics were compared between groups using Student’s t-test for normally distributed continuous variables and Wilcoxon rank sum test for non-normally distributed variables. Categorical variables were compared using chi square and Fisher’s exact test as indicated.
Kaplan Meier survival analysis was used to compare actuarial survival between patient cohorts. Multivariable logistic regression was performed to evaluate the risk-adjusted predictors of one-year posttransplant mortality. Statistical analysis was performed using Stata version 16 (StataCorp, College Station, TX, USA).
