I did not say, that I evaluated the studies. I just wanted to exemplify that with very little effort one could find studies. I don't think it is my job to evaluate every study on any subject. If I were interested in the details and interested in discussing the actual content (not the meta layer of discussion quality) I would first look at meta studies and see were they lead me, though. So sorry for posting examples that there are studies without the disclaimer, that I did not check the strength of any of those.
