Short answer
CiteFlow can place two selected research PDFs in one comparison workflow while source-linked notes keep population, method, result and limitation visible. Draft synthesis from those checked fields, then audit each claim against its attached evidence.
When to use this method
PDF readers expose documents one at a time; a project comparison workflow aligns source-linked evidence on shared dimensions.
Before you start
Collect at least two relevant PDFs and write one comparison question. Use the same fields for every paper. A method explains how a study was carried out, a result reports what it found and a limitation explains what the result cannot safely show.
How we checked this guide How comparison and source-tracing behavior were checked.
- What we reviewed
- Reviewed shared comparison fields, tags, exact search, evidence provenance and cross-paper synthesis in CiteFlow.
- What we confirmed
- Tags and source-linked notes preserve a comparison structure, but the app does not judge study quality or make different methods equivalent.
- Important limit
- Two studies can report similar outcomes for different populations or methods. Keep those differences explicit in the comparison matrix before drafting a shared conclusion.
Compare evidence on shared dimensions
Select two relevant papers
Compare papers that answer the same question or explain why the comparison is useful. Do not force unrelated methods or populations into one conclusion.
Choose comparison dimensions
Define tags or headings for population, method, data, result, limitation and relevance before reading the entire set.
Collect comparable evidence
Use shared tags and exact search to locate passages for each dimension, then inspect every result in its source context.
Separate claim from interpretation
Mark what the authors state, what the evidence shows and what you infer for the review.
Write from the comparison
Group agreement, disagreement and evidence gaps, then return to source pages before finalizing a synthesis statement.
Comparison errors
- Comparing only abstracts
- Treating semantic similarity as agreement
- Treating different populations or methods as equivalent
- Writing synthesis claims without reopening cited pages
Checkpoint: Synthesis checks
- Use the same population, method, result, limitation and relevance fields for every paper.
- Confirm both PDF titles before using the two-document comparison.
- Label author claims, observed results and your interpretation separately.
- Trace each synthesis statement to linked passages and record unresolved contradictions.
