To help you, here is a list of high-quality peer reviewed journals:
Peer review refers to the process whereby experts in a given field help judge the value of a relevant work or ideas that they were not part of creating. The primary function of peer review is gatekeeping—selecting the best from a pool of submissions. It also serves, however, as a source of constructive criticism, whereby expert feedback by peers can be taken into account to improve ideas, research proposals, and papers.

In general, meta-analysis involves the systematic identification, evaluation, statistical synthesis, and interpretation of results from multiple studies. It is useful particularly when studies on the same or a similar subject or problem present contradictory findings, thereby challenging interpretation of the collective results.
