How does Authory retrieve articles for journalists whose publications do not freely distribute their content online?
We will scan the reference lists of reviews and retrieve articles for additional studies.
Potential limitations of the study are related to the database used to retrieve articles.
We searched PubMed, Web of Science, and Wanfang databases with identical strategies to retrieve articles.
Moreover, the search did not only retrieve articles relevant to the nursing field or to North America and Europe.
In step 2, a search strategy was devised to retrieve articles related to this aim.
While efforts were made to contact authors to retrieve articles from our search, twenty-seven full-text articles were irretrievable.
All references of the remaining articles were reviewed to retrieve articles initially missed in the search syntax.
Each retrieved article was assessed by the authors, and the article's references were searched for additional reports.
In addition, references from retrieved articles were screened to identify possibly missed studies by literature retrieval.
