Abstract text
This workshop will offer practical advice on searching registers, documenting the search process and managing records obtained from registers. It will be based on information contained in Chapter 6 of the Cochrane Handbook for Systematic Reviews of Interventions (Searching for Studies), of which the presenters are co-authors.

The workshop will begin with an overview of the development of trials registers, followed by online demonstrations of key registers highlighting their search features and downloading options. There will be hands-on exercises if facilities permit or a discussion of search approaches to use with less well-developed interfaces, if online access for the participants is not available.
Trials registers provide information on current and recently completed trials and trials results registers provide data from completed trials. Trials registers are important for systematic reviews because they provide opportunities to reduce publication bias. Trials can be identified at an early stage and followed through to completion. Trial protocols can be assessed for relevance and increasingly trial results are recorded within the registers. Trials registers present challenges in terms of their identification, efficient searching, record de-duplication and record management.
