The impact on survival of nod2 variants. Impact is shown for the complete cohort (n = 576; A-C) and the subcohort of nonmalignant disorders (n = 72; D-F). Kaplan-Meier probability of survival plots as a function of presence () or absence (…) of NOD2/CARD15 polymorphisms (A,D), of presence () or absence (…) of unilateral recipient-side gene variants (B,E), and of presence () or absence (…) of unilateral recipient-side SNP13 (C,F).
