What was measured

Kaplan-Meier estimate of an event of death estimated at five years post-transplant. 95% confidence intervals were calculated from the logit transform of the Greenwood variance. The transformation was necessary to keep the estimate within the probability space of 0 to 100%.

Analysis population: Study cohort separated into four disease groups.

    group Description
    Log-rank test. (Mantel-Haenszel test). Null hypothesis is all four groups are statistically from the same population. Alternative hypothesis is that at least one of the groups is from a population different from the remaining groups. Anticipated sample-sizes comparing Active ALL (anticipated N= 12) with the combined AML patients (anticipated N=38) was deemed to be too small for formal hypothesis testing.
