Description
A clinical trial to evaluate the efficacy of maintenance
chemotherapy for acute myelogenous leukaemia was conducted by
Embury et al. (1977) at Stanford University. After reaching a
stage of remission through treatment by chemotherapy, patients
were randomized into two groups. The first group received
maintenance chemotherapy and the second group did not. The aim
of the study was to see if maintenance chemotherapy increased the
length of the remission. The data here formed a preliminary
analysis which was conducted in October 1974.
Usage

Format
A data frame with 23 observations on the following 3 variables.
- time
The length of the complete remission (in weeks).
- cens
An indicator of right censoring. 1 indicates that the
patient had a relapse and so 'time' is the length of the
remission. 0 indicates that the patient had left the study or
was still in remission in October 1974, that is the length of
remission is right-censored.
- group
The group into which the patient was randomized. Group 1
received maintenance chemotherapy, group 2 did not.
