  1. From Literature Searching to Literature Analysis How to Create Insight with Search Results

  2. Session Goals Go beyond the results of your literature search Use an analytical technique to segment and give meaning to a batch of search results Use visualization strategies to turn textual results into pictures

  3. Today we will learn… • Subject Analysis • Chronological Review • Subject Mapping • Literature Review • (Author) Content Analysis

  4. What is Literature Analysis? Simple definition: Doing something to make sense of search results. Deeper definition: Looking into search results for themes, patterns, and trends which answer specific questions about the resulting data set.

  5. Subject Analysis Most literature searches are built on subject or keyword searches It makes sense that analyzing literature results also focus on subject searches

  6. Chronological Review Answers the questions: When did this research begin? How much material was written in each year (or another time period)?

  7. Chronological Review Method of Analysis: • Count the number of articles written for each year (or month) • Graph using a line or bar graph to visualize the trend in number of articles from past to present

  8. Chronological Review Example pubmed– (headache disorders [MeSH Major Topic]) AND ("1960“ [Date - Publication] : "3000"[Date - Publication])

  9. Chronological Review Example

  10. Subject Mapping Answers the questions: How does this subject (these subjects) relate to shoulder fields? Are the correct search terms being used?

  11. Subject Mapping Method of Analysis: Draw a schematic of your search terms using the thesaurus or controlled vocabulary of your database. Try to map terms both broader and narrower than your search term. Have you considered any of these related terms in your search strategy as alternative language? Does this map suggest broader or narrower terms that should be used in the search instead?

  12. Subject Mapping Example

  13. Literature Review Answers the questions: Who are the major contributors to this subject field? What is their contribution or the point made in their writing?

  14. Literature Review Method of Analysis: Sort through search results, ranking by number of articles written by each author. For each author, summarize the topic of their research or their contribution to the subject field. A literature review may also review all authors in the field if you want to be comprehensive rather than selecting only the most prolific authors.

  15. Literature Review Example pubmed – (migraine disorders[MeSHMajor Topic]) AND (“2013“[Date - Publication] : “2014"[Date - Publication]) Allais, G (4) – study of treatment for menstrual migraine, preliminary trial on ginkolide B, migraine and pregnancy internet study, comparison of treatment with triptans on menstrual migraine Silberstein, SD (8) – gastroinstinal symptoms, use of botulinum toxin A as migraine treatment, full-spectrum treatment and endpoint goals, review article on dihydroergotimene, study of CGRP gene in cause of migraine, clinical trial of gabapentin Tepper, DE (4) – use of nasal sprays to treat migraine, use of NSAIDS to treat migraine, treatment of chronic migraine, investigation of migraine and obesity

  16. Author Content Analysis Summary of themes used by a single author Comprehensive analysis of the author’s work over their career, not limited by time period or subject area May be used in conjunction with Literature Review after key authors are identified for “deeper dive”

  17. Author Content Analysis Method of Analysis: Scan search results and begin grouping them into broad categories Count (use tick marks) results that fall into each category May be used in conjunction with Literature Review method textual summary analysis for further insight into each broad category

  18. Author Content Analysis Example pubmed – (migraine) AND (“Silberstein“[Author]) Medications (75%) Genetics (5%) Side effects (3%) Co-morbidities (7%) Surgical treatments (7%) Chronic migraine (3%)

  19. Author Content Analysis Example

  20. Today we learned… • Subject Analysis • Chronological Review – best to understand WHEN the majority of the research was written • Subject Mapping – best to understand WHAT TERMS should be included in your final search strategy • Literature Review – best to understand WHO the major contributors to the field are and WHAT their contributions are • (Author) Content Analysis – best to focus on a single author and analyze the THEMES of their writing over a long period of time
