About Data Extraction
"As in systematic reviews, scoping review authors should only extract data items that are relevant to the scoping review questions. Therefore, potential data items of interest can be structured around the PCC framework. Further items for data extraction will depend on the purpose and reasoning behind conducting the review. For example, the individual items could be related to the study design, such as whether it was a randomized controlled trial (RCT); the methods used for conduct; and outcome measurement approaches. Alternatively, it could include definitions, statements, or arguments surrounding a concept. It could be interventions studied, their application, dose, duration, and frequency."

Data Extraction Guidelines
- Create a standardized data extraction form
- Document guidance for the form will be used and applied and ensure all team members understand
- Describe the planned data extraction and develop a draft extraction form for your protocol
- Test your draft data extraction form on each type of study included in the review
- Have at least 2 researchers independently extract the data from each included study
- Develop a plan for resolving disagreements in data extraction
- Recommendations for the extraction, analysis, and presentation of results in scoping reviews
This paper expands on existing JBI scoping review guidance. It clarifies the process of extracting data from different sources of evidence; discusses what data should be extracted (and what should not); outlines how to analyze extracted data, including an explanation of basic qualitative content analysis; and offers suggestions for the presentation of results in scoping reviews.

This section of the JBI Manual describes best practices for data extraction in systematic reviews.
Data Extraction Tools
Which ever tool you decide to use, the data must be available upon publication.
Covidence: allows you to create and publish a data extraction template with text fields, single choice items, section headings and subheadings, perform dual reviewer data extraction, review extractions for consensus and export data extracted to a csv file.

Spreadsheets or Database Software (Excel or Google Sheets):
Spreadsheets or database software can be used to create custom extraction forms. Spreadsheet software (such as Microsoft Excel) has functions such as drop-down menus and range checks which can perform data collection efficiently and help to prevent data entry errors.
Review Manager (RevMan) is Cochrane's software for preparing and maintaining Cochrane reviews. RevMan facilitates preparation of protocols and full reviews, including text, characteristics of studies, comparison tables, and study data. It can perform meta-analysis of the data entered, and present results graphically.
Survey or Form Software (Qualtrics, Poll Everywhere or Google Forms)
These tools allow the reviewers to create custom forms with a variety of question types to collect data in a standardized format
Data Analysis
Data extraction is os often the first step in data analysis, as you will structure your extraction to suit the analysis you intend to do. You should limit the amount of interpretation in a scoping review. If your project requires more sophisticated analysis methods, that may be an indication that a systematic review is a better fit for your project.
What Types of Analysis Are Appropriate for Scoping Reviews?
- Descriptive statistics
- Basic qualitative content analysis
Remember: regardless of how you choose to analyze and present your data, you always need to do a narrative synthesis as part of a scoping review!
