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).
