Manual-input analyses
It is recommended that authors set up their analyses at the protocol stage. See Standard C21 ‘Planning the synthesis of results’ of the MECIR Manual.
Create a manual-input analysis
Follow the instructions to create analysis groups and analyses. Select 'Manual’ when you are prompted to choose between creating an analysis based on study data or manually entered data. Then, set the analysis options.
Once you have created the first manual analysis in the analysis group, you can edit the group labels –which only apply to manual analyses- of the analysis group.
Add studies and study data to the analysis
Once you have defined the analysis options, go to the analysis 'Data' tab and select ‘Add data row’ to add a study from the list of included studies.
In case of a long list of studies, you can use the filter to find them more easily.
Enter the data by:
- typing the data manually into the table cells,
or
- pasting data -in tabular form- from an external source.
You can also copy data from an analysis in RevMan and paste it into an external file. More information is available on copying and pasting data into and from analyses.
To delete a row, click the ‘Action’ button for the row that you want to delete and select ‘Delete data row’.

Add a footnote to data rows
You can add a footnote to one or more of the studies included in the analysis. Go to the analysis ‘Data’ tab and select the 'Action' button of the relevant study row. Select ‘Edit footnote’ to add the footnote. Each footnote will be numbered.
Once you have entered the footnotes, check how they will appear in the forest plot to ensure that they are fully visible by previewing your submission or viewing a version.
Please keep footnotes as concise as possible and check that they are fully visible in the forest plot graph.
Forest plot settings
The published review will display the forest plot based on the forest plot settings defined in each analysis ‘Graphs’ tab.
Once you have created and set up your analysis, go to the 'Graphs' tab to adjust how the forest plot is displayed.
You can sort studies by study ID, year of study, weight, effect size, or risk of bias item.
The scale is set to 100 by default, but you can change it to optimize the presentation of your results if needed.
If you want to include the risk of bias summary in the forest plot, select ‘Show risk of bias summary’.
