Covidence has two tools for extracting data. Extraction 1 and Extraction 2.

Over the past year, we have enhanced Extraction 1 to create a tool specifically designed for intervention systematic reviews. These improvements were based on extensive feedback and research from experienced systematic reviewers. 

Extraction 1 is now the best data extraction tool for intervention systematic reviews, which is why it is set as the default option for systematic reviews.
