Clinical trials training

Exercise 1

Searching trials registers requires us to be flexible and adapt our approaches.

1. Go to the AustralianNew Zealand Clinical Trials Registry and explore how you would best search this resource.

   1. Try to identify what is the default operator when two terms are used in the search

   2. How can you do a phrase search?

   3. Can you nest search terms using parentheses?

   4. Can you use truncation?

   5. Can you search in individual fields?

   6. Can you save searches?

   7. Can you export tagged output that could be loaded into bibliographic software such as EndNote?

2. Go to the UK trial register Be Part of Research

   1. Try to identify what is the default operator when two terms are used in the search

   2. How can you do a phrase search?

   3. Can you nest search terms using parentheses?

   4. Can you use truncation?

   5. Can you search in individual fields?

   6. Can you save searches?

   7. Can you export tagged output that could be loaded into bibliographic software such as EndNote?

3. Go to the Pfizer trial results website

   1. Search for Lyrica - how many results do you find?

   2. What types of documents does it provide?

   3. Compare the information in documents to consider whether each document has unique value.

Exercise 2

This exercise is designed to give you some hands-on experience of searching ClinicalTrials.gov and the WHO Portal (ICTRP).

Here are some example Ovid MEDLINE searches.

• Consider which concepts you will use to search for trials within ClinicalTrials.gov, ICTRP and the Cochrane Library

• Test out the search terms that you might use in each resource
