Systematic review and meta-analysis tool
Web tool for conducting a systematic review and meta-analysis following the PRISMA 2020 workflow, using the public OpenAlex API as the sole bibliographic search source.
Features
The pipeline covers all eight stages of a systematic review, from search to export:
- OpenAlex search: query builder (keywords, dates, document types, open access), result count preview before import, background import for large searches (up to 10,000 results) with live progress tracking.
- Deduplication: automatic by OpenAlex ID at import time (a work found by multiple searches is never duplicated).
- Title/abstract screening: full-screen card interface, include/exclude/maybe, keyboard shortcuts (← → ↓/M), exclusion reasons, history with undo.
- Full-text screening: same mechanics, restricted to records included at the previous stage, with a direct link to the full text (DOI).
- PRISMA flow diagram: generated automatically from screening decisions, PNG/SVG export.
- Data extraction: project-configurable fields (text, number, boolean, list), editable grid for included studies.
- Meta-analysis: effect sizes (mean difference, Hedges' g, odds ratio, risk ratio, or custom measure), fixed- or random-effects pooling (DerSimonian-Laird), forest plot, I², τ², Q, p-value.
- Export: CSV datasets (records, extraction, effect sizes), automatically assembled Markdown report, PRISMA 2020 checklist worksheet (27 items) to document ahead of publication.
- Project management: create, delete (with confirmation and full cascade of associated data).
