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.

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.

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
