Question: Meta analysis for the incidence risk ratio?

[Daniel Wing JC]

Dear Colleagues,
I would like to inquire how to do forest plot on my dataset between intervention arm and control arm for meta-analysis for the incidence risk ratio; and would like to learn from this example, but I don’t know how to do. I would be grateful if any experts could offer me some helps.

end

For calculation for the incidence risk ratio?
I am looking forward to hearing about your comments.
Thanks. Best regards, Daniel

I'm not sure exactly what you are asking for. The screenshot you attached was made using Stata 17's built in -meta- suite of commands, so I will assume that you have access to that. You can run -help meta- from Stata 17 and then click on the PDF documentation to follow along with a software-free introduction to meta-analysis, and then learn about how -meta- works, specifically.

Failing that, you would be well advised to consult any good textbook on the topic of meta-analysis. The software choice of that book shouldn't matter, it seems you need to understand the underlying statistics.
