Let me get this straight, I believe one needs to read a paper to get it straight.

But I fully understand your knee-jerk reaction. That was my reaction when I read the title too. However, it seems to be a surprisingly well-thought analysis where all your points are answered (controlled).

If I read it more thoroughly I'll likely find flaws on the statistical methods. But it's not like the authors didn't have common sense.

Edit: unfortunately, enough people had the same knee-jerk reaction to get this thread flagged. We really need a way to vouch a thread.
