EFS by randomized regimen for patients with intermediate risk ALL.
The probability of surviving event-free is higher for patients randomized to DDI, compared with those randomized to DIVPI or DI. The numbers of patients remaining in follow-up at 6 and 9 years, respectively, were 282 and 38 on DI; 268 and 33 on DIVPI; and 299 and 45 on DDI.
