Look, if you are so interested in this, why don't you do the research yourself?
I literally just googled "meta-analysis psychoanalysis" and the very first link that came up [1] was, surprisingly, a meta-analysis about psychoanalysis which concluded the abstract with the following phrase:
"In contrast to previous reviews, we found the evidence for the effectiveness of LTPP [long-term psychoanalytic psychotherapy] to be limited and at best conflicting."
I'm not interested in wasting more of my time on this topic, so don't expect any more replies.
