The probabilities of OS and PFS in the DCA group compared with CA groups. 1 thin line, DCA group; 2 thick line, CA group. DFS, 26.5vs. 22.8months, p = 0.90; OS, 28.4months vs. 28.1months, p = 0.19. The 12-month progression-free survival (PFS) for the MDS group and tAML group was 62.3% and 43.7%, respectively. The 24-month DFS for the DCA group and CA group was49.6% and 61.8%, respectively.
