Data extraction can be challenging. It requires you to go back to your chosen articles and highlighting the relevant information that will answer your research question. Normally this involves extracting the data related to your chosen framework and its components e.g. PICO, PEO etc. To standardise and improve the validity of the results, it's crucial to create a data extraction form or table (Bettany-Saltikov, 2012, p. 96).

You may have read or seen some of the data extraction software available (e.g. Covidence). Unfortunately, we currently do not have any licences for this software at University of Dundee.
Alternative options include creating a table, form manually that suits your review.
