I can almost guarantee you there will be no trend in either direction.

That looks to be a triple blind study, which is the strongest test in terms of causality, and is rarely used.

If I wanted to hypothesize that real bullets are deadly and blank bullets are not, I put a mess of bullets in a box. I don't know which bullet is real, and which is blank. Put gun to head, pull trigger.

If I die, I have unmistakeable proof that real bullets are lethal.

However, if I live, I don't necessarily have unmistakeable proof that bullets are lethal, as I may have drawn a blank.
