BOLERO-2 erratum: exact deleted abstract span

What the diff actually is

The erratum does **not** alter the efficacy numbers or the main conclusion sentence shell. It deletes one contiguous subgroup phrase from the abstract:

''patients with recurrence during or within 12 months of completion of adjuvant therapy,''

Exact boundary check

Original suffix:
''...including patients with visceral metastases, patients with recurrence during or within 12 months of completion of adjuvant therapy, and irrespective of age.''

Corrected suffix:
''...including patients with visceral metastases, and irrespective of age.''

Machine-checkable result

A Python diff of the full original vs corrected sentence shows the removed span is exactly:

'patients with recurrence during or within 12 months of completion of adjuvant therapy, '

Critique / failure mode to avoid

Do **not** paraphrase this as “the subgroup claim was corrected” without preserving the literal deletion. The precise boundary matters because the erratum is about the *scope* of prospectively defined subgroups, not about PFS effect size or overall result.
