Identifying a Topic and Conducting the Literature Search
Published in Lisa Chasan-Taber, Writing Grant Proposals in Epidemiology, Preventive Medicine, and Biostatistics, 2022
The first step is identifying the correct database to search. Typically, for proposals in epidemiology and preventive medicine, PubMed which encompasses the MEDLINE database is the primary choice (https://www.ncbi.nlm.nih.gov/pmc/about/intro/). PubMed is a free resource supporting the search and retrieval of biomedical and life sciences literature. PubMed facilitates searching across several National Library of Medicine (NLM) literature resources including MEDLINE. The PubMed database contains more than 32 million citations and abstracts of biomedical literature. It does not include full-text journal articles; however, links to the full text are often present when available from other sources, such as the publisher's website or PubMed Central (PMC). For some epidemiologic studies that involve a psychosocial exposure or outcome, the database PsycINFO may also be relevant. Google Scholar or Lexus/Nexus may also be useful. Refer to your library's website for a description of the searchable databases to which your institution has access or contact a reference librarian for further assistance.
Researching Medical Literature and Other Information

Healthcare journal articles are occasionally free of charge through PubMed. Links directly to the article archived in PubMed Central or in the actual journal are clearly displayed when an article is available for free. Searching the individual journal’s website archives may also allow access without charge. Individual journals determine the amount of time before articles may be accessed without a subscription fee. ClinicalKey and UpToDate have access to full text articles from many journals available without an additional charge to the basic subscription fee.

The placenta of 84 women with PE and 103 unrelated age and ethnicity matched normotensive pregnant women were recruited from the Department of Obstetrics and Gynecology of Ali-ibn-Abi Taleb Educational Hospital of Zahedan University of Medical Sciences. The placentas of all participants were collected after delivery. The ethical committee approved the study, and informed consent was obtained from patients and control women. The research has been carried out in accordance with the Declaration of Helsinki (2013) of the World Medical Association. Preeclampsia was diagnosed as hypertension (≥140 mmHg systolic or ≥90 mmHg diastolic on two or more measurements at least 6 h apart) and proteinuria (≥0.3 g/24 h or ≥+1) on a urine dipstick after 20 weeks of gestation. Women with twin or multiple pregnancies, hydrops fetalis hydatidiform mole, heart diseases, renal disease, diabetes, liver dysfunction, and all systemic diseases were excluded from the study.

Biomed Res Int. 2014; 2014:497031. PubMed PMID: 24877103. Pubmed Central PMCID: 4020502. All participants had a random triple code and the information about the test is masked from the technician (blinded experiment).
Solicitation for article submission by electronic journals
Published in Baylor University Medical Center Proceedings, 2018
Somedeb Ball, Jonathan Kopel, Robert Alexander, Kenneth Nugent
One author (KN) retained all emails received between April 4, 2017, and October 9, 2017, that invited him to submit an article to an electronic journal. Each website was reviewed to determine whether or not the journal had an association with a medical organization or a medical publisher, the primary subject focus of the journal, the types of articles published, the first year the journal had publications, and the number of articles published in 2017 through September 2017. In addition, the website and other online resources were reviewed to determine whether or not the journal was listed in PubMed or PubMed Central, in the DOAJ, and/or in Beall’s predatory journal list and to record publication fees. We did not review content, citations related to the articles, or the reported impact factors of these journals.
The availability of raw data in substance abuse scientific journals
Published in Journal of Substance Use, 2019
Antonio Vidal-Infer, Rafael Aleixandre-Benavent, Rut Lucas-Domínguez, Andrea Sixto-Costoya
A study of the supplementary material of the original articles was performed through a search in the PubMed Central repository. PubMed Central is the most used free full-text repository in biomedicine. Only articles with supplementary material were retrieved. A parallel analysis was performed by two researchers in order to collect and code the information to a Microsoft Excel spreadsheet. The number and types of files were registered. In cases where a compressed file, such as a .zip or .rar file, was found, it was opened to check what kinds of files it contained. After finishing the analysis, a comparison of both sheets was carried out and, in case of disagreement, a third collaborator untied.
