Meta-analysis must upload the document screening process.

As we all know, document screening is an important part of meta-analysis, and the flow chart of document screening is an essential part of meta-analysis articles. This paper mainly explains how to draw a document screening flow chart through RevMan.

RevMan provides two kinds of literature screening charts for reviewers: the flow chart based on PRISMA (only the number of studies searched or screened needs to be filled in the corresponding part) and the blank flow chart (which needs to be made by itself).

First, a document screening flow chart is generated. Click Graphics-Add Graphics.

Select the appropriate flowchart according to your own meta-analysis requirements, and then click Next. A flowchart can be generated. Double-click the flowchart to enter the editing state for editing.

The following is the display of the initial state of the two flowcharts:

Research flow chart (PRISMA template)

Flowchart (blank)

Take the blank flow chart as an example to make it.

For the flowchart made by RevMan, the height of each rectangular box cannot be changed, but the width can be changed at will and dragged. When editing text, you can also enter a specific value in the picture width.

It should be noted here that after the flow chart is completed, save it directly, and the flow chart shown in the following figure may appear.

So we can copy the flow chart into the Word document first, and then make further editing to increase the clarity.
