Metan

[Macarena Lozano]

Hello,

I am starting to do a meta-analysis and I use the following syntax: "metan b se, eform" where b is the logarithm of the OR and SE is the standard deviation.

Then I get a table with the 8 articles included, but it doesn't give me the heterogeneity value and I get the following error: matrix operators that return matrices not allowed in this context
Error in metan_output.DrawTableAD

I am using Stata version 15. I have tried it on my computer with several colleagues and only one of them has no problems, but I would like it to work on my computer. Could it be a missing package?

I appreciate any help

For the benefit of others: Macarena has been in touch with me directly, and the issue is the same as described in these threads:

I have patched the code and released it to SSC and GitHub. Users of metan running Stata 15 or older should update to this new version (version 4.08.1 12jul2024).

Kind regards,
David.
