As a Swede I can tell you that whatever research comes out of these institutions will be biased. These institutions suffer to a large degree of self-hatred due to some nasty shit that they've contributed to over the years. For that reason, they try to always publish crap like in order to champion diversity and deny their vicious history. It's basically like how Germans react to their history with Hitler. Merkel had no choice but to welcome Islam as a part of German Society and find post-facto justification for it in order for her not to be seen as "repeating the mistakes of the past". Douglas Murray called it "The True Legacy of Hitler" and it is present in Sweden as well.

Edit: I am not saying that these findings are fake, but rather that these institutions are not as credible as you might think they are when it comes to think kind of topic. Politics drives the discourse in most of them, not science!
