Zotero → BibTeX Export

# 1. In Zotero: File → Export Library → BibTeX (.bib)
# 2. Or use Better BibTeX plugin (recommended):
#    - Install: https://retorque.re/zotero-better-bibtex/
#    - Right-click collection → Export Collection → Better BibTeX
#    - Check "Keep updated" for auto-sync

# 3. Clean up common Zotero artefacts with bibtexparser (Python)
pip install bibtexparser

python3 << 'EOF'
import bibtexparser
from bibtexparser.bwriter import BibTexWriter
from bibtexparser.bparser import BibTexParser

with open("exported_zotero.bib") as f:
    parser = BibTexParser(common_strings=True)
    db = bibtexparser.load(f, parser=parser)

# Remove Zotero-specific fields
fields_to_remove = {"file", "abstract", "keywords", "mendeley-tags", "note"}
for entry in db.entries:
    for field in fields_to_remove:
        entry.pop(field, None)

writer = BibTexWriter()
writer.indent = "  "
with open("references.bib", "w") as f:
    f.write(writer.write(db))

print(f"Exported {len(db.entries)} entries to references.bib")
EOF

arXiv Submission Preparation

# Step 1: Build final PDF and verify it looks correct
latexmk -pdf main.tex

# Step 2: Check for undefined references / citations
grep -i "warning" main.log | grep -i "undefined"

# Step 3: Flatten \input / \include (arXiv requires single .tex or explicit includes)
# Use latexpand (part of texlive-extra-utils)
latexpand main.tex > main_flat.tex

# Step 4: Strip comments (arXiv processes the source; hidden comments can leak)
python3 -c "
import re
with open('main_flat.tex') as f:
    src = f.read()
# Remove comments but keep \% (escaped percent signs)
src = re.sub(r'(?<!\\\\)%[^\n]*', '', src)
with open('main_flat.tex', 'w') as f:
    f.write(src)
print('Done.')
"

# Step 5: Ensure all figures are included and named without spaces
# PDF figures preferred; EPS and PNG also accepted

# Step 6: Bundle
mkdir arxiv_pkg
cp main_flat.tex arxiv_pkg/ms.tex
cp main.bbl       arxiv_pkg/   # pre-compiled bibliography (biber → .bbl)
cp -r figures/    arxiv_pkg/
tar -czf arxiv_submission.tar.gz -C arxiv_pkg .

# Step 7: Test-compile the tarball in a clean directory
mkdir test_compile && cd test_compile
tar -xzf ../arxiv_submission.tar.gz
pdflatex ms.tex
pdflatex ms.tex
ls -lh ms.pdf

We sincerely thank the Editor and all three reviewers for their constructive
feedback. We have addressed all concerns and believe the manuscript is
substantially improved. Changes in the revised manuscript are highlighted
in \textcolor{teal}{teal}.

\section*{Reviewer 1}

\reviewer{1}{1}
\revcomment{%
  The sample size justification is unclear. How was the effect size of 0.5
  determined for the power calculation?
}
\response{%
  We agree that the justification was insufficiently detailed. The effect size
  was derived from a pilot study ($n = 20$) conducted by our group (now cited
  as Smith et al., 2022). We have added a paragraph in \S2.3 (Methods) with the
  full calculation: assuming Cohen's $d = 0.50$, $\alpha = 0.05$, and 80\%
  power, a minimum of 64 participants per arm is required. Our enrolled sample
  ($n = 70$ per arm) provides $>85$\% power.
}
\change{%
  Revised \S2.3, lines 112--119. Added citation to Smith et al. (2022).
  Updated supplementary Table S1 with full power curve.
}

\reviewer{1}{2}
\revcomment{%
  Figure 3 is difficult to read in greyscale. Please ensure figures are
  accessible to colourblind readers.
}
\response{%
  Thank you for raising this important point. We have replaced the red/green
  colour scheme with the Okabe--Ito palette, which is safe for all common
  forms of colour-vision deficiency. We have also added pattern fills to bars
  to ensure legibility in greyscale.
}
\change{%
  Figures 3, 4, and 5 updated with new colour palette. Legend updated
  accordingly.

\section*{Reviewer 2}

\reviewer{2}{1}
\revcomment{%
  The Discussion overstates the clinical implications. Please temper the
  language regarding translation to practice.
}
\response{%
  We appreciate this important caution. We have revised the Discussion
  (\S4.3) to clearly delineate the current evidence base from speculative
  clinical translation. Phrases such as "will improve clinical outcomes"
  have been replaced with "may inform future clinical trials".
}
\change{%
  Revised \S4.3, lines 287--301.
