Association of SNP rs17473423 with aGVHD, survival, and relapse. (A) Cumulative incidence of grade III-IV aGVHD. The P value and HR were calculated in a competing risk regression analysis in which death before aGVHD was considered a competing risk. (B) Kaplan-Meier curves for overall survival according to the number of mismatching alleles. The P value and HR were calculated by Cox regression analysis. (C) Cumulative incidence curves of relapse of AML/MDS (left), ALL (middle), and CML (right) in which death before relapse was considered a competing risk.
