Fig 6. Effect of KIR genotype matching on cGVHD & relapse-free survival (cGRFS) among C1/x recipients.
As with cGVHD, KIR genotype matching segregated only the recipients having one or two C1 bearing HLA-C allotypes for differences in cGRFS in a multivariate Cox proportional hazards regression that accounted for covariates for both GVHD and relapse. No effect on relapse free survival (RFS) or overall survival (OS) was noted.
