Numbers tested are based on the most recent data point for all subjects who are alive past 6 months (n=42) plus the 2 subjects who died after 1 year (total = 44)
2
Numbers tested are based on all subjects who have data over 2 years after transplantation. Anti-A data are for all subjects who are not blood type A and did not receive an A thymus. Anti-B data are for all subjects who are not blood type B and did not receive a B thymus. A total of 30 subjects are included in these isohemagglutinin studies.
