^{^a}

Data are reported as median (range).

The P‐values present the comparison between the young donor and middle‐aged donor groups.

^{^†}

The P‐values present the comparison between the middle‐aged donor and old donor groups.

^{^‡}

The P‐values present the comparison between the young donor and old donor groups.
