Aim of this user manual
This user manual is a guide for the usage of Meta-Essentials. It is not a guide on how you should search for studies, which studies you should include, nor for how the results of the meta-analysis should be interpreted. We have written a separate text on these matters (see Hak, Van Rhee, & Suurmond, 2015).

The first step when using Meta-Essentials is to choose the appropriate workbook for the meta-analysis. Then, this manual discusses how to insert data, how to perform a basic meta-analysis and to generate a forest plot, how to run a subgroup analysis, a moderator analysis, and various publication bias analyses. Also, the calculations 'behind' the sheets and the applied statistical methods are discussed, however, knowledge or understanding of these methods is not required for using Meta-Essentials. Next, the manual discusses those instructions that apply only to specific workbooks. This manual concludes with discussing guidance for how output of Meta-Essentials can be adapted for inclusion in a report.
The workbooks of Meta-Essentials are compatible with Microsoft Excel 2010, 2013 and 2016. Older versions of Microsoft Excel might work fine in some cases, but some formulas and formatting features are not supported by these older versions. The workbooks of Meta-Essentials are unfortunately not compatible with OpenOffice, the online versions of Microsoft Office (365), or Google Docs. These programs do not correctly calculate all formulas and cannot display all figures.
