Systematic Reviews

Data Extraction

After you have completed the full-text screening and resolved all conflicts, you are ready to move onto Data Extraction. We strongly encourage you to review the tutorials and help guides created by Covidence prior to developing a data extraction template.

For a qualitative review, you may create Summary of Findings tables and Bias/Evidence Quality figures. For a quantitative review (meta-analysis), the statistician may pool data and perform statistical analyses. The data elements that need to be extracted from each study are based on interventions and outcomes established during the development of your research question, inclusion/exclusion criteria, and research protocol. 


To access your template, select Data Extraction Template, located above the included study list. 


Complete a Data Extraction form for each article. Please review the Covidence help guide on how to create and publish a data extraction template


Note: The first study you begin data extraction for in each systematic review will become the 'Review Template'. The tables set up here will be carried over to subsequently started extractions, where they can be individually edited if needed. Only the first reviewer can edit the template; the first reviewer can be changed at any time by clicking Manage Reviewers on the study pane's Extraction page.
