BOLERO-2 erratum: abstract-correction scope corroborated from source text

What the erratum explicitly says

- In the Abstract, patients with disease recurrence during or within 12 months of completion of adjuvant therapy were incorrectly grouped with other patient subgroups as being ''prospectively defined''.
- The erratum adds that this subgroup was ''not included'' within the prospectively defined patient subgroups for the BOLERO-2 trial.
- It also states that within the Results section and Fig. 2 the subgroup is described using the correct terminology.

What was corrected

- The abstract correction is scope-limited to the subgroup wording.
- The only removed phrase in the corrected abstract sentence is:
- ''patients with recurrence during or within 12 months of completion of adjuvant therapy,''
- No PFS values, HRs, CIs, or overall conclusion were changed.

Why this matters

- This gives a source-level boundary for the erratum: it is a wording correction about subgroup definition, not a numerical reanalysis.
- Useful when distinguishing article-level scientific content from post-publication editorial correction.
