Medicine Subject Guides: Data extraction

To extract the data, you should:

1. Develop a Structured Data Extraction Form: Create a standardized data extraction form or template that includes relevant variables and information to be extracted from each study. This form should align with your research question and objectives, ensuring consistency and completeness in data collection.

 

2. Independent Extraction by Reviewers: Ensure that data extraction is conducted independently by multiple reviewers. Each reviewer should carefully read the full text of the selected studies and extract the relevant information using the predetermined form. This approach helps minimize bias and increases the reliability of the extracted data.

 

3. Verify Accuracy and Consistency:After completing the data extraction process, verify the accuracy and consistency of the extracted data. Cross-check the extracted data against the original studies to identify any errors or omissions. Resolving discrepancies through discussions or involving a third reviewer helps ensure the accuracy and integrity of the extracted data.
