In our original article [1] the multivariate models outlining the association of cohabitation with breast cancer recurrence and mortality were over-adjusted, as models also included marital status, which is used to define cohabitation. This has now been corrected.

  1. 1

    In Fig. 2, the 5 years and overall adjusted IRRs and CIs of recurrence were incorrect and stated as 0.89 (0.61—1.29) and 0.85 (0.60—1.19) in the published manuscript, respectively. The corrected estimates are 1.21 (0.90—1.63) and 1.09 (0.83—1.43).

  2. 2

    In Fig. 3, the 5 years and overall adjusted IRRs and CIs of mortality were incorrectly stated as 1.03 (0.67—1.60) and 1.02 (0.70—1.47), respectively, instead of 1.55 (1.10—2.20) and 1.41 (1.05—1.88).

The correct figures are given ahead.
