2.3. Statistical Analysis
Descriptive statistics were used for the analysis of patients’ characteristics including demographic factors such as age, gender, diagnosis, stage, status at transplant, number of relapses, number of deaths, cause of death, and conditioning regime. The Kaplan–Meier method with the log-rank test was used to estimate OS and EFS, and prognostic risk factors were analyzed using univariate analysis. All reported p-values were for two-sided testing, and a p-value of ≤0.05 was considered statistically significant for all analyses. All statistical analyses were performed using SPSS for Windows, version 24.
