For statistical analysis, white patients were compared with a combined group of other ethnic groups, and other ethnic groups were individually compared with white patients alone. Remission rate was defined from start of therapy to the end of course 2; treatment outcome (OS, EFS) was estimated from end of 2 courses.

SE indicates standard error.
