Abstrackr vs CADIMA

Abstrackr is a free web tool for screening citations in systematic reviews. It supports solo work, blinded team screening, pilot rounds, and conflict resolution. After about 100 labels, machine learning ranks remaining citations by predicted relevance. A live PRISMA flow table records screening thresholds, resolved conflicts, exclusion reasons by tag, and analysis of the model’s stop point. Citations can be imported from PubMed, Scopus, or Embase, or uploaded as RIS and CSV files. The service deduplicates records by DOI and PMID and can merge remaining near-duplicates. Results export as CSV or RIS, with a full JSONL download for DuckDB queries. Blinding starts enabled, and changes are logged with user, reason, timestamp, and project snapshots. Member and Leader roles have no stated team-size limit, while reminders arrive 7, 4, and 1 day before deadlines. No installation is needed, and the site directs methodology questions to its community forum.

CADIMA is a free web application for planning, conducting, and documenting systematic reviews, systematic maps, and other literature reviews. It accepts review questions from any research discipline and lets review teams work together worldwide, with no stated limit on reviewers at different stages. During screening, records can be allocated automatically while allowing independent and parallel assessment. CADIMA removes duplicate records automatically and supports bulk PDF uploads. It records the review process in detail, while its evidence synthesis database provides guidance and hosts synthesis data. The site describes planned archiving for review and evidence-map data and modules. Access data are used for statistical purposes and are not passed to third parties, according to the privacy policy. A scientist-and-programmer team handles questions, and user feedback informs further development. CADIMA is published by the Julius Kühn-Institut in Quedlinburg, Germany. The footer identifies version 2.2.4.2, dated April 2023.
