Conclusion

After five years of therapy, 3484 women were randomly allocated to two or five further years of Anastrozole treatment. After eight years, there was no difference in survival between the groups (hazard ratio 0.99, 95 per cent confidence interval 0.85 to 1.15, P=0.9), but women who had the longer course were more likely to have a bone fracture.
