AIS grade before transplantation, AIS grade 1 year after transplantation, motor level before transplantation (R/L: right side/left side), motor level 1 year after transplantation, AIS grade at the initial evaluation of AIS examination in the hospital after SCI, AIS grade 1 year after initial assessment, motor level at the initial evaluation, motor level 1 year after initial evaluation, and —motor levels C1 to C3. There was no zone of partial preservation below the neurological level of injury in complete SCI patients in both groups at baseline.
