The Cite button makes it easy to retrieve styled citations that you can copy and paste into a document.
To cite an article you find in PubMed Central, click on the Cite button (1) and then chose the required citation format (2). For this class you will use APA format. Then you can copy the citation into your references list or document.
Note: In all citation styles, there are certain capitalization rules that machines cannot handle. For example, there is no way to identify proper nouns, acronyms, abbreviations, etc., that is 100% accurate and complies with all rules at all times. Capitalization of article titles and other citation elements should be checked for compliance with a particular reference style when required.
