Extraction 1 is designed specifically for intervention reviews. It includes specific sections which allow you to collect data for interventions and outcomes. You can add custom fields if you wish to collect more data.
Extraction 2 is more flexible in terms of the types of data you can collect. It is fully customizable and includes single-choice fields, multiple choices, and tables. However, it doesn't include specific sections for interventions and outcomes and data do not export to RevMan. It's more suited for all other projects, including scoping reviews and qualitative reviews.
