Demonstration of interaction between expression level of patients’ nonshared HLA-C and residue 116 and residue 77/80 match status for nonrelapse mortality. Patients’ low-expression mismatched allotypes were defined as HLA-C*07 and C*03; high-expression mismatched allotypes were defined as HLA-C*01 and C*14. Each 95% CI is denoted by black bars. Numbers in parentheses indicate the patients who died of nonrelapse causes of the total number of patients in each of the 4 groups as defined by residue 116 match status (A), residue 77/80 match status (B), and level of expression of the patients’ mismatched HLA-C.
