Systematic Reviews: Synthesising and reporting

Synthesising your results

Once you have selected the relevant studies you will need to put all your findings together using textual or statistical methods. 

Tools for data extraction 

Please note the university does not subscribe or provide support to any of the extraction tools however you may able able to use limited time free versions of those which are not freely available.

The amount and type of data collected and the number of collaborators extracting it are the two factors to take into account when choosing extraction tools for your project. Excel or Google Spreadsheets may be the best option for smaller or simpler projects, while systematic review software platforms can provide support for larger or more intricate data.

It is recommended that you pilot your data extraction tool, especially if you will code your data, to determine if fields should be added or clarified, or if the review team needs guidance in collecting and coding data.

Reporting your results

PRISMA - Preferred Reporting Items for Systematic Reviews and Meta-Analyses provides a structured framework to reporting systematic reviews and meta-analyses.  

When referring to the PRISMA, the developers recommend using journal article citations rather than referring to the PRISMA website or, failing that, cite one of the original publications of the PRISMA Statement or PRISMA Explanation and Elaboration.
