This would seem as suspicious a result as helmets reducing head injuries is.
It wasn't clear for hockey helmets either. There's no way to quantify the risk people take. But on an accident by accident basis, helmets offer additional protection.
EDIT: Are these studies discussing only injuries by committed road cyclists, or injuries to people on bicycles in general?
