Impact of donor KIR3DL1/HLA-B subtype combinations on relapse incidence and overall survival. This figure shows the univariate comparisons for the cumulative incidence of relapse (left panel) and overall survival (right panel) in the framework of the 3-group model of patients classified based on their donors’ KIR3DL1/HLA-B subtype combinations according to Boudreau et al.¹⁹  The P values represent the score tests of univariate Cox regression models.
