While data extraction might sound difficult and complicated, it is a fairly straight-forward process. The goal of data extraction is to find the data you need from individual studies, then isolate and remove that information to be further examined.
What types of data should you be looking for when doing data extraction? Include information about the data extraction process, eligibility criteria, study methods, study participants, the study intervention, the outcomes, the results, and any other relevant information included in the study.
