Raw data reanalysis of multiple studies consider as meta analysis? I am struggling with the question of  how to define my research.
I download raw data (RNA sequencing data) from multiple studies and I am going to analyze again them together as they " brought from one study".
Can I call it a meta analysis of some kind?
Thanks a lot!

You are thinking about doing an 'individual participant/patient data meta-analysis' (IPDMA). It's a bit more involved though than just combining some datasets and pretending they are one large study. To start, you need to respect the multilevel nature of the data. For a very thorough coverage of the topic, see:
