This document discusses the processes and fields involved in maintaining a study-based register. It outlines 5 main processes for the register - search, download, de-duplicate, screen, and studify records. The webinar focuses on extracting study details ("coding") to populate fields in a study form. Examples of fields for the dementia group include study name, registration ID, status, design, intervention, and funding. Standardizing these fields and using controlled vocabularies from sources like ClinicalTrials.gov and WHO is discussed to facilitate searching and linking data.

• Show me all trials which have been funded by industry AND
are completed but have not yet published

#1 industry:FT
#2 completed:SS
#3 results not available:SSI
#4 #1 AND #2 AND #3
10. Discussion
• ClinicalTrials.gov study form – makes sense to
use the same?
• WHO portal – 20 pieces of study metadata –
use that?
• Controlled vocabs – MeSH, Emtree, others –
use those?
• Linked data project – implications?
• RevMan Characteristics of included studies
