How to create a PRISMA flow diagram

1. Add a PRISMA flow diagram

To add a PRISMA flow diagram, go to 'Figures', then click on 'Add Figure'. Under 'Figure type' select 'Flow diagram'.

2. Edit the content

Add the data to the default text and it will show in the view to the right. You can add or delete sources to account for different types of sources by clicking 'Add source'. You can delete a source by clicking 'Delete' in its related row.

Note that you can only edit the flow diagram according to the PRISMA guidelines.

3. Add a caption

As in all figures in RevMan Web, you can add a caption for your PRISMA flow diagram.

4. Working with the flow diagrams that don’t follow the PRISMA guidelines

If a flow diagram is not following the PRISMA guidelines, you can open it to view, but you will not be able to edit it in RevMan Web (see an example of such a diagram below). If you want to make any edits, you will have to recreate the flow chart according to the PRISMA guidelines.

5. Create a PRISMA flow diagram for a review update

If you are updating the review, it may happen that you know only the final number of included studies in the previous version. In that case, you can check the ‘Alternative PRISMA flow diagram’ box and the flow diagram will change to include an additional identification node and a box in the diagram (# studies included in previous version of review). You can then type in the numbers from your updated search and join the number of studies included in previous version with the number of studies identified as eligibile in the review update (#new studies included).

You can edit the content as in the normal PRISMA flow diagram (see point 2 above). You can also switch back to the normal PRISMA flow diagram by unchecking the box.

Note that the alternative PRISMA diagram should be used only for review updates of previously published reviews where the full search history is not available.
