the width of the confidence interval lines.
3. Additional functions to display outcomes in the Excel spreadsheet:
MATauSquare and MAQIndex.
4. More options can now be saved to become user-preferred defaults.
5. Several enhancements to the meta-analysis of prevalence:
a. Introduction of three different options for transformations:
none, logit, and double arcsine.
b. Introduction of multi-category prevalence meta-analysis.
c. A ‘normalise’ option to make sure multiple category pooled
results sum to 1.
d. An additional parameter for the MaPooledEffect,
MaPooledEffectLCI, and MAPooledEffectHCI functions to determine the
category number.

f. Addition of a section to this User Guide on the Meta-analysis of
Prevalence.
