Current misconception 3: that subgroup-specific trial mortality results often provide a good basis for individualising patient care.

For, if the overall results are similar but much more highly significant for recurrence than for mortality, subgroup analyses with respect to the former may be more stable and may provide a better guide as to whether there are any major differences between subgroups in the proportional risk reduction produced by treatment ( EBCTCG, 2005a , 2005b ).
