Here are some key points about sensitivity and specificity in literature searching:
- Sensitivity refers to the proportion of relevant records that are retrieved by the search. A highly sensitive search aims to retrieve as many relevant records as possible, even if it also retrieves some irrelevant records.
- Specificity refers to the proportion of retrieved records that are relevant. A highly specific search aims to retrieve few irrelevant records, but it may fail to retrieve some relevant records.
- Searching by title alone will be more specific but less sensitive than searching the title, abstract, and keywords fields.
- Using narrow search terms or limits will increase specificity but reduce sensitivity.
- Boolean AND increases specificity but reduces sensitivity by only retrieving records that contain all
Here are the key differences between searching Medline via OVID vs PubMed:
- In PubMed, searches use boolean operators like AND instead of / between terms
- PubMed does not have exploded subject headings, so you need to search each term individually
- In PubMed, text words are searched with [tiab] instead of .tw
- PubMed does not have a built-in limit for human studies, so you need to add that filter yourself
So in summary, the syntax is slightly different but the concepts are the same - you're searching for the same epidemiological study designs in both databases.
1. Clarify the research question.
2. Search relevant databases and other sources using a structured search strategy with keywords, synonyms, and Boolean logic.
3. Screen search results according to inclusion/exclusion criteria and select studies for full-text review.
4. Critically appraise the quality of included studies.
5. Extract key data from included studies and synthesize findings.

Advice to rest in bed versus advice to stay active for acute
low-back pain and sciatica
The objective of this review is to determine the effects of advice to rest in bed or stay active for patients
with acute low-back pain or sciatica.
The following comparisons will be made:
• Bed rest versus staying active
• Bed rest versus other treatments (besides staying active)
• Shorter periods of bed rest versus longer periods of bed rest
• Staying active versus other treatments (besides bed rest)
• Comparison between different forms of advice to stay active (e.g. avoiding bedrest, staying active)

Editor's Notes
What is data? What’s the issue? = fragile – data format, elusive (particularly just when you need it!) = part of research methodology & part of legacy – people might want to build on your work = how much of what you produce will you want/need to keep Where will you record/store it? = multiple copies, multiple places (confidential data permitting) = Key things to consider here are: the names you give files and folders use of tags, or information in file properties whether you need to conform to any conventions in your field How will you share it? = why should you? Reputation Funding Impact Re-use = where? Dspace? Use repositories and data centres Choose open or controlled access Consider embargoes and redactions if necessary
