Cross-tabulation between TCE-X and TCE-FD

	TCE-X
TCE-FD	Nonpermissive, n (%)	Permissive, n (%)	Total, N (%)
Nonpermissive	1118 (40.9)	161 (5.9)	1279 (46.8)
Permissive	49 (1.9)	1402 (51.3)	1451 (53.2)
Total	1166 (42.8)	1564 (57.2)	2730 (100)

Percentages refer to the total number of 2730 8/8 HLA-matched DPB1-mismatched donor–recipient pairs analyzed in this study. The 210 discordant assignments as TCE-X permissive and TCE-FD nonpermissive (n = 161) or vice versa (n = 49) were due to the presence of DPB1*06:01 and/or 19:01, which were classified as TCE group 2 and 3 by TCE-FD and TCE-X, respectively (n = 205) or to the presence of a DPB1 allele that was classified as TCE group 1 or 2 by TCE-FD but was attributed to TCE group 3 by TCE-X because of missing data (see Supplemental Table 1) (n = 5).
