Levamisole and 5FU in Stage C colon cancer

The colon data set is used in D. Lin, Cox regression analysis of multivariate failure time data, the marginal approach, Statistics in Medicine 13:2233-2247, 1994. This data is not exactly the same as in Lin's paper -- we have more follow-up. One can get close to Lin's results by truncating follow-up on 15 Aug, 1989.

The Moertel paper discusses results from both stage B2 and stage C patients. This data file contains only the stage C results. Patients 1-929 are from the main trial, and the remainder from an older trial; Lin uses only the larger study.

The remaining variables are only available for study 1
