Note: experience in the field does not necessarily increase the accuracy of this process. The exact procedure may vary according to your resource capacity. For example, you may have a team of 10 extractors in 5 pairs of 2 extracting data from chunks of the included material, if managing a large corpus.
Just like all other stages of a systematic review, 2 data extractors should extract data from in each included reference. The synthesis approach(es) (e.g., meta-analysis, framework synthesis) that you intend to use will inform data extraction.
Data extraction, sometimes referred to as data collection or data abstraction, refers to the process of extracting and organizing the information from each included (relevant) study.
