Metan command: How to convert proportion to the percentage?

[Brian ER]

Hi all,
I'm using Stata 17
how to change the effect size from proportion meta-analysis to percent format using metan?

This is my current code:

metan all_mut Total, proportion by( Country ) randomi transform(ftukey) label(namevar= Study ) labtitle(Study) dp()

I would be thankful if somebody helped me.
