Statistical Analysis

Numerical variables were expressed as means ± SD and categorical variables were presented as values and percentages. The Pearson's Chi-square test and Fisher's exact test were used to compare categorical variables between patient groups, whereas the Student's t-test and Mann–Whitney U test were employed for continuous variables, depending on the variable distribution as assessed by the Shapiro–Wilk test. Possible associations between numerical variables were preliminary explored using Spearman's rank correlation coefficient (for couples of variables with non-normal distribution). The Kaplan–Meier method was applied to estimate survival in each patient group and distributions of survival times were compared with the Log-rank test. Logistic regression analysis with a stepwise method was performed to assess the relationship between complications after transplantation and variables of interest (for instance possible predictors), both categorical and numerical. Analyses were conducted with the MedCalc Software Version 17.4 (Ostend, Belgium) and a P-value < 0.05 was considered significant.
