Relation of GATA2 expression with survival in morphologic and genetic AML subgroups. Kaplan-Meier estimates for pOS, pEFS, and pDFS in AML patients with FAB-M5 morphology (A), inv(16) (B), or high WT1 expression (C). Patients with high GATA2 expression were compared with patients with normal GATA2 expression using a log-rank test. High GATA2 expression was associated with worse outcome. P < .05 was considered statistically significant (2-tailed testing). Patient characteristics are described in supplemental Tables 5 through 7.
