Can the MTAG results be used for a meta-analysis? #203

For example, we analyzed 3 GWAS statistics from different ancestries (EUR, EAS, AFR), and produced 3 MTAG results. Can we perform a cross-ancestry meta-analysis for these MTAG results?

I'm confused by your question. You are using MTAG within an ancestry across several traits and then you'd like to meta-analyze with a trait across ancestries?

Thank you for your reply. For example, 1.we used MTAG within 2 traits (trait1 and trait2) from EUR. 2.we used MTAG within 2 traits (trait1 and trait2) from AFR. 3.we used MTAG within 2 traits (trait1 and trait2) from EAS. The above analyses generated trait1_MTAG_EUR, trait1_MTAG_EAS, and trait1_MTAG_AFR. Lastly, we would like to perform a cross-ancestry meta-analysis within trait1_MTAG_EUR, trait1_MTAG_EAS, and trait1_MTAG_AFR.

This sounds reasonable to me. I can't think of why you shouldn't be able to do this (though sometimes I'm not creative enough to anticipate problems that I haven't tested...)
