More places to look.

NLM bibliographic records. Ingested directly through E-utilities; no institutional subscription needed.

Biomedical papers, preprints and linked full text. Records overlap with PubMed and are deduplicated.

Trial registrations, status, sponsors and posted-results indicators. Registration is not evidence of benefit.

DOI metadata, funding and update relationships. Supplemental title-based discovery; no abstract republication.

Open scholarly metadata and links to open versions. Bounded supplemental discovery; API allowance may require a key.

Direct search across papers, theses and other scholarly works. No bulk access; never scraped.

Read full text and article-specific licenses. Availability does not mean unrestricted reuse.

Systematic reviews and controlled-trial records. Some full text requires access.

Multilingual evidence-synthesis discovery. Search on the source site.

Physiotherapy trials, reviews and guidelines. Use the source’s search and ratings.

Clinical evidence discovery. Access varies by feature.

Citation discovery and related papers. API ingestion is a future adapter.

University and repository research. API access and reuse terms must be configured before ingestion.

Academic repositories, including theses. Use the source search.

Research outputs, projects and repositories.

International open-access literature, including substantial Latin American research.

Latin American and Caribbean health-sciences literature. Try local-language terms too.

Japanese scholarly publications and full text.

Open-access journal and article discovery.

Data, software, preprints and repository deposits. A deposit is not necessarily peer reviewed.

Study registrations, projects and preprints. Check the record’s review status.

Health-sciences preprints. Preliminary work, not peer-reviewed clinical guidance.

Biology preprints. Preliminary findings and mechanisms.

Physics, optics and computational preprints.

International trial registrations. A registration is not a published result.

Cross-registry trial discovery. Search availability and export access vary.

European clinical-trial information. Not all device studies fall within its scope.

Australia and New Zealand trial registrations.

Systematic-review registrations; protocols are not completed findings.

Specialist association resources. Read the source, dates and scope of recommendations.

Specialist education and research resources. Source-level disclosure is required for any imported material.

User-requested alternative AI resource. No public ingestion API or content license verified. Check every factual claim against original evidence.

User-requested alternative publisher with commercial products. Articles and interviews are not equivalent to controlled research. Content is not ingested.

Alternative research aggregation. Follow citations to originals; summaries and claims have not been appraised here.

Independent evidence summaries; topic coverage and access vary.

Post-publication discussion. Comments are leads to examine, not automatic verdicts.

Independent curator’s PBM bibliography and topic tables. Follow the original papers; request permission before copying the compiled dataset. Historic summary is not a current systematic review.

Detailed PBM overview with linked references, safety discussion and topic navigation. Editorial synthesis, not original research. Membership-supported publisher.

Complementary-medicine database from the Carstens Foundation with expert and quick searches. Broad CAM coverage, not a dedicated PBM index. Confirm update cadence before relying on completeness.

Naturopathic and integrative-health research programs; links to original publications and trials. Institutional source, not a comprehensive PBM repository.

Natural-medicine research and institutional study discovery. Follow each project to its registration or publication. Broad scope; PBM coverage not established.

Integrative cancer-care education and therapy reviews. Use supportive-care context and original citations; do not conflate integrative care with a cure claim.

Brain and transcranial PBM studies curated by a device manufacturer. Useful primary-paper leads. Disclose commercial ownership and verify devices and funding in each paper.

Condition-specific research digests and training from a PBM manufacturer. Some downloads request contact details. Bibliographies are leads, not independent appraisal.

Device measurement, irradiance and dosing commentary from a seller. Useful technical questions and citations; verify measurements and commercial interests.

A retailer’s searchable study selection with PubMed links and a link to Heiskanen’s database. Shows that working source-linked competitor libraries do exist. Do not inherit its positive-result labels without review.

Alternative-health publisher with PBM coverage and commercial interests. Treat as commentary and citation discovery. Original claims and suggested protocols are not endorsed or ingested.

Professional herbal education and resources. Useful only for broader natural-health discovery; not a PBM evidence database.

Historical nutrition and orthomolecular medicine archive, including papers and commentary. Not a dedicated PBM source. Appraise the individual study and do not treat an archive entry as a clinical endorsement.

Alternative-medicine articles, practitioner perspectives and archives. Some access is paid. Discover citations without importing articles or treating opinion as controlled research.

University-affiliated integrative-medicine publications. General integrative scope; PBM-specific coverage must be checked.

Integrative-health reporting, study summaries and practitioner education. Source availability varies; PBM-specific coverage not established.
