Hi, I'm trying to do a meta-analysis of 4 studies (microarrays and RNA-seq). I'm using the rma function from the metafor package, with the DerSimonian-Laird (DL) method. If I want to identify differentially expressed genes, do I have to calculate the adjusted p-values from the p- values I have obtained? Do you think DL is a suitable method? Thank you so much for your help!
