studies
Format alone does not decide safety. Export quality does.
This study compares file-type outcomes and shows where each format fails in real diagnostic patterns.
Observed failure patterns
Image-only PDFs, malformed text layers, and DOCX field-boundary collisions.
Interpretation
No format is universally safe. The safer variant is the one with stronger parser agreement.
Practical recommendation
Test both formats when possible and submit the version with higher extraction confidence.
