Interview with Elizabeth S. Draper, Prof., University of Leicester, Project Leader
Duration: 8min
1. Introduction and Core Minimum Dataset
Elizabeth S. Draper, Prof.
Duration: 16min
Summary
An introduction to the RECAP cohorts and the work carried out by WP3 documenting the cohorts and their data. Additionally, an overview of the rationale and methods for the ongoing development of a core minimum dataset for preterm birth research are presented.
Learning goals
- the approach taken to identify, collate and harmonise data for the RECAP preterm project;
- which birth cohorts are included in the RECAP preterm project in terms of their geographical location, the year the birth cohort was initiated AND the ages at which follow-up assessments and additional data collection was carried out
- the processes & principles used to develop a core minimum dataset for use in future preterm birth cohorts
2. Metadata catalogue
Helen Collins, Dr.
Duration: 9min
Summary
An introduction to study level metadata, how and why we developed the Metadata Catalogue and where to find it on the RECAP Preterm Data Platform.
Learning goals
- What is study level metadata?
- Why is a metadata catalogue important?
- How we developed the RECAP Preterm metadata catalogue
- Where is cohort metadata found on the RECAP Preterm platform?
3. Anatomy of a data dictionary
Deborah Bamber
Duration: 12min
Summary
An introduction to the development and purpose of a data dictionary and data schema, and why these are key to facilitating harmonisation and analyses.
Learning goals
- Understand what the RECAP Preterm data dictionary is and why it was developed
- Understand why and how the RECAP Preterm data schema was developed
- Understand how data mapping is carried out
- Appreciate the complexities of curating data from multiple cohorts and variable mapping
- Be able to prepare your own data dictionary and know how to access a data dictionary template, the data schema, and variable mapping instructions.
4. Introduction to Harmonisation
Charlotte Powell, Dr.
Duration: 21min
Summary
