A data extraction form should be developed early in the review planning process using the research question and inclusion criteria to customize the form to meet the needs of the project. Carefully and thoroughly extract all relevant information from studies to be included in your systematic review. Relevant information will depend on the research question and and whether you are using quantitative or qualitative information, and/or the conventions of the journal to which you will submit for publication. The information extracted will predominantly relate to your study inclusion criteria; and may cover definition or conceptualization, measures/key variables, research design, participants, year of publication, data/results, study design, study setting, etc. (Siddaway et al., 2019).
Commonly extracted fields for SRs include:
