About Us
Physicians and scientists created Cogent Medicine to put compelling research and interpretation at your fingertips. This site provides registered users with strata of reading suggestions, expert commentary, and integrated search and archive tools, layered over the MEDLINE® database.

Our intent is to encourage users to read, by means compliant with any copyright restrictions, the full text article referred to by bibliographic citations and author abstracts. Abstracts are displayed only to communicate the minimum amount of information necessary to motivate users to seek out and read the full text article. Abstracts cannot be construed as a comprehensive representation of the contents of the full text article. Abstracts, including copyright notices within the abstract when supplied by the publisher, are always displayed with the citation author, title, and source information. Cogent Medicine neither implies nor expresses a creative or proprietary role in the abstracts or any other part of the MEDLINE® record.

MEDLINE®
MEDLINE® is the National Library of Medicine's (NLM) premier bibliographic database covering the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and the preclinical sciences. MEDLINE® contains bibliographic citations and author abstracts from more than 4,000 biomedical journals published in the United States and 70 other countries. The file contains over 11 million citations dating back to the mid 1960's. Coverage is worldwide, but most records are from English-language sources or have English abstracts.

NLM's MEDLINE® is reproduced and distributed by Cogent Medicine at its own expense, in full compliance with its Lease Agreement with NLM. No endorsement by the NLM, the National Center for Biotechnology Information, the National Institutes of Health, Cogent Medicine, or any of the products or services advertised on this system is intended or should be inferred.

Notice to Users Who Search MEDLINE® at Cogent Medicine
Unless otherwise prohibited, organizations or institutions may download small amounts of NLM-produced citations for redistribution. For MEDLINE, this is about 1,000 per month or 12,000 records for each year of coverage. Since NLM makes corrections and enhancements to and performs maintenance on these records at least annually, you should plan to replace or correct the records once a year to ensure that they are still correct and searchable as a group.

NLM databases are produced by a U.S. government agency and as such the contents are not covered by copyright domestically. They may be copyrighted outside the U.S. Some NLM produced data is from copyrighted publications of the respective copyright claimants. Users of the NLM databases are solely responsible for compliance with any copyright restrictions and are referred to the publication data appearing in the bibliographic citations, as well as to the copyright notices appearing in the original publications, all of which are incorporated by reference. Users should consult legal counsel before using NLM-produced records to be certain that their plans are in compliance with appropriate laws.

All records must be identified as being derived from NLM databases.
