Extraction stage

Systematic review data extraction that lands in a checkable evidence table

Turn included papers into structured evidence rows covering study design, population, outcomes, and limitations, with each extracted field traceable to its source paper.

What this tool helps you do

Data extraction is the stage where each included study is reduced to structured fields such as design, population, sample, interventions, and outcomes. LitSynth generates an evidence card per included paper and assembles them into an evidence table, so extraction errors surface as visible gaps rather than silent fabrications in the draft.

Editable workflow

From research question to a review you can inspect

Each stage stays visible, so you can revise the scope or evidence choices before generating again.

  1. 1

    Start from the included set produced by screening.

  2. 2

    Generate structured evidence cards for each paper.

  3. 3

    Inspect the assembled evidence table and flag gaps.

  4. 4

    Generate the synthesis from the checked evidence only.

Best for

  • Building an evidence table from an included paper set
  • Checking extracted fields against source papers before drafting
  • Keeping failed or incomplete extractions visible instead of hiding them

Not a replacement for

  • Risk-of-bias scoring to Cochrane standards
  • Statistical pooling or meta-analysis of extracted values

Limits stated on this page

  • Automated extraction still requires reviewer verification against the source text.
  • LitSynth does not perform Cochrane-grade risk-of-bias assessment.
  • Quantitative results are extracted as reported; statistical re-analysis is out of scope.

Keep evidence decisions visible

LitSynth treats AI as support for a review process. You keep control of which papers enter the evidence set and which claims need another check.

Generate one evidence card per included paper.

Review study design, population, outcomes, and limitations per paper.

See extraction failures flagged with reasons instead of omissions.

Carry the checked table into the synthesis draft with citations intact.

Questions researchers ask

What fields does the extraction capture?

Each evidence card covers study design, population and sample, interventions or exposures, primary outcomes, quantitative results where reported, and limitations. The assembled evidence table presents these fields side by side for comparison.

What happens when extraction fails on a paper?

The paper stays in the table with the failure marked and a reason attached. LitSynth does not silently drop failed extractions, because a missing row is a decision a reviewer should make consciously.

Can I edit the extracted data?

Yes. The evidence table is inspectable before synthesis, and the workflow is designed for you to catch extraction problems before they propagate into the draft.

Does this replace a manual extraction spreadsheet?

For most rapid and PRISMA-lite reviews, the generated table covers the fields a spreadsheet would, with the added benefit that every row stays linked to its source paper. Formal reviews with registered protocols may still require independent double extraction.
