Systematic (searching for a) Review
This document provides an overview of the systematic review process. It begins with developing the research question using PICO(S) or SPICE frameworks. This is then translated into search terms and concepts. The document outlines searching databases and other sources, as well as screening and critically appraising the literature. It discusses data synthesis and publication bias. Tips are provided for searching, such as using wildcards, adjacency searches, and combining concepts. Challenges like books, grey literature, and other languages are noted. Reference manager software is also mentioned.

- 18. Abstract There isample evidence for the existence of an association between sleeplessness and worry. Not much is known, however, concerning the nature of this relationship. Therefore, a study was conducted investigating the causal relationship between sleeplessness and nocturnal worry. A 2 x 2 (Worry x Induced sleeplessness) analysis of covariance design was used. The first factor consisted of a subject variable defined by scoring either high or low on a trait measure of worry (the Penn State Worry Questionnaire) and the second factor consisted of 300 mg caffeine or placebo. A total of 96 female undergraduate students participated. The dependent variables comprised measures of nocturnal worry (the Night-Time Thoughts Questionnaire) and subjective and objective sleep parameters. Overall, caffeine caused an increase in nocturnal worry and sleeplessness. A significant interaction effect occurred between Worry and Induced sleeplessness on one of the objective sleep parameters, but no other interaction effects were significant. The results suggest that worry may occur as an epiphenomenon of sleeplessness.

Editor's Notes
- #4 EBM-(evidence based) guidelines. Synopses & Syntheses*: a synopsis is a summary and critical appraisal of one article, whereas synthesis is a summary and critical appraisal of a topic (which may answer several questions and may cover many articles). Systematic Reviews (a systematic summary and critical appraisal of original studies) which may or may not include a meta-analysis. Original Studies.
- #5 Purposes for a review To place work(s) in the context of how it contributes to an understanding of the subject under review To identify new ways to interpret previous research To resolve conflicts across seemingly controdictory studies Avoid reinventing the wheel, or worse, the flat tire Source: Booth, A., Papaioannou, D., & Sutton, A. (2011). Systematic approaches to a successful literature review. Sage.
- #7 P Patient/Population - What people or patient group do I want information on? I Intervention – What is the intervention (treatment, cause, prognostic factor) of interest? C Comparison – What is the main alternative to compare with the intervention (if necessary)? O Outcomes - What do I hope to accomplish? What could this exposure affect?

- #38 Problematic aspects of Pubmed - Limited amount of truncation (*) possibilities (only 600 word variations) - Quotation marks with asterix doesn’t work (compare "word combination*" with word combination* and word and combination* ) - Some word combinations won’t work because Pubmed does phrase indexing instead of word indexing (e.g. "right not to know"[tiab] )
- #42 Grey literature is informally published written material (such as reports) that may be difficult to trace via conventional channels such as published journals and monographs because it is not published commercially or is not widely accessible
