Disease-free survival and heterogeneity in subgroups by minimisation variables

Categories are listed as recorded at randomisation; ten patients in the 3 month group and 15 patients in the 6 month group could not be allocated to high risk stage II or stage III based on T/N data recorded at randomisation. *These estimates differ slightly because the underlying multivariable Cox model on which they are based includes parameters for other minimisation variables, as well as those factors relating to stage; the increased flexibility in the expanded stage model allows the influence of these parameters on the high risk stage II estimates to modify.
