This article introduces you what the New PubMed database retrieval method is, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Systematic review / Meta analysis refers to a research method that comprehensively collects all relevant studies and strictly evaluates and analyzes them one by one, and then processes the data qualitatively or quantitatively to draw a comprehensive conclusion. In the process of guiding students, it is found that beginners often encounter many common problems in the process of learning. This official account hereby opens a column to answer, hoping to learn and exchange Meta analysis with you and grow together. If there is anything inappropriate, please criticize and correct it. In this issue, we share the retrieval methods of the new version of PubMed database.

01

Overview

Let's see what PubMed has updated. Preview the summary in the summary on the results page: click the set button in the results display interface, and then select Abstract, you can see the search results are displayed in the form of a summary, showing a very comprehensive information page browsing summary: after clicking the title to enter the page details, you can see that PREV RESULT and NEXT RESULT appear on both sides You can directly turn the page of the search results and use the sidebar to browse the records: the sidebar adds RESULTS BY YEAR in addition to the original filter, you can move two small dots to limit the year of publication of the document to your favorite format citation: PubMed supports the direct citation format, click Cite, you can appear the cited results and support the AMA,MLA,APA,NLM format, and you can also download ris format to import document management software. Share via social media or permanent links: click Share, support sharing to Facebook and twitter, and copy article links.

Display up to 5 external tool icons: the full-text link will support up to 5 icons to meet the needs of possible access to the full text. Access to all content through mobile devices: you can use your mobile phone to access the PubMed database and achieve adaptation. Can the old version still work after PubMed update?

At present, the new version of PubMed and the old version can coexist, as long as you choose the corresponding URL: PubMed updated version: https://pubmed.ncbi.nlm.nih.gov/,PubMed old version of https://www.ncbi.nlm.nih.gov/pubmed, but in 2020, the updated version of PubMed will become the default. What if you master the retrieval method for the updated version of PubMed?

Retrieval method

Next, we use the retrieval strategy of osteoarthritis to demonstrate the retrieval and export of literature:

"osteoarthritis" [MeSH] OR "osteoarthr*" [Title/Abstract] OR "degenerative arthritis" [Title/Abstract] first enter the MeSH database, click MeSH Database on the page, enter osteoarthritis, check the first record and click Add to search builer on the right, you will see "Osteoarthritis" [Mesh] in PubMed Search Builder, click Search PubMed. Next, click Advance in the display interface of the results to enter the field Title/Abstract in the advanced search interface, enter the search word osteoarthr*, in the box, click Add, and you will see that osteoarthr* appears in Query box [Title/Abstract]. Similarly, enter "degene rat ive arthritis". At this time, you need to note that because it is the second word, to choose the logical relationship with the first word, click the drop-down arrow and select Add with OR. Finally, you can see the search form of (osteoarthr* [Title/Abstract]) OR ("degenerative arthritis" [Title/Abstract]), and then click Search, or you can click the drop-down arrow to select Add to history. Finally, the topic search results and free word search results are combined in the retrieval history interface, respectively, click Actions, select Add query, Add with OR, and finally you can see the search form in Query box, click Add to history, and finally you can see 89887 search results in the search history interface, and then click the number to enter the interface displayed by the search results.

The display interface of the results only supports two groups of sorting methods: Best match (default) and Most recent. The previous reduction in the number of Best match has been solved, and the export of documents is more user-friendly. The only drawback is that a maximum of 10,000 records are supported. Click Save,Selection to select All results, and also support All results on this page (the page document) and Selection (you selected). Format selects RIS format, and the saved format is opened by default with EndNote to import. Since PubMed does not support hierarchical export, you need to ensure that the final search results are less than 10000 when making Meta analysis (I believe there are not that many, otherwise the screening will be exhausting)

In addition, it is worth mentioning that comments, similar articles and quoted articles have been added to the abstract display interface, which will increase the experience of reading the literature. Currently, documents will be retrieved after logging in, so functions such as custom filters and create reminders cannot be used, and the favorite plug-in for ScholarScope to display impact factors is also invalid. So you are PubMed's update. Do you like it or not? About what the New PubMed database retrieval method is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
