You can find a study out there addressing almost any question you might ask. The problem with these is that they are often too broad. And that's a tough thing to trust since conducting research in schools is such a challenge. In the end, we're not going to get a yes or no answer. I could tell you that, in perusing the studies and reports, I've seen more positive than negative results, but that too would be suspect.
