Abbreviation: CI, confidence interval.
Fisher’s exact test was used to compare engrafted and non-engrafted predictors.
Student’s t-test was used for to determine if age was a predictor of engraftment.
^aOnly significant variable in multivariate analysis.
^bPatients with no available information on differentiation were not included in the calculation.
