I am using JASP for the first time to perform a meta-analysis comparing PCI vs CABG. In the software, I started off with classical meta-analysis. I entered effect size, effect size standard error, method (DerSimonian-Laird), study labels. However, under covariates and factors, I do not understand which parameters to place.
- Since I am comparing PCI vs CABG my parameters are PCI number, PCI events, CABG number, and CABG events. What goes under covariates and what goes under factors?
- My understanding is use random effects model over fixed effects model. Is that correct?
- Is it possible to do meta-regression in JASP?
