Literature search

Three free databases, strings you can re-run, a screening log you own

Nothing searched yet.

This documents a search: sources, exact strings, dates, criteria, every record and your decision on each. It is not an appraisal — suitability and contribution (MEDDEV 2.7/1 rev 4 Appendix A6) are the evaluator's judgment and are not recorded here. Embase, Scopus and Web of Science are not searched; they need a subscription. Abstracts are free; full text of a paywalled paper is not, and an open-access link is shown where a source knows one.

1 · What to search for

Device or device type — one term per line

Synonyms and brand-free generic names. Phrases are quoted for you.

Condition, procedure or outcome — optional, one per line

ANDed with the device terms when present.

FDA product code (for the record)

Published from

Published to

Inclusion criteria — one per line

Exclusion criteria — one per line (these become the reasons you can pick)

OpenAlex API key (optional, free; stays in this browser)

OpenAlex pauses anonymous search when its index is under load and says so; a free key from openalex.org lifts the pause. The key is sent only to OpenAlex and never printed in the protocol, so the protocol stays re-runnable by anyone.

Sends the terms and dates to PubMed, OpenAlex and ClinicalTrials.gov. Nothing else, nowhere else.

2 · What each source holds, and what was retrieved

Run a search to see counts and the exact strings sent.

3 · Screening — title and abstract, your decision

Screener (written into the export; not sent anywhere)

Every identifier links to the record at its source; read it there. A draft of this table is kept in this browser so a reload does not lose it; the export is the record.

4 · PRISMA count

Counts appear once a search has run.
