Several answers can be clinically valid, images must be interpreted, and overlap metrics such as BLEU or ROUGE match expert opinion poorly.

The result is heavy over-redaction, which hurts readability and the downstream value of the data. Xu et al. (Oxford and Microsoft, BioNLP 2026) frame the fix as post hoc refinement.
