>I hardly think they'd still recommend the maneuver still if it was "bunk". The mayo clinic doesn't recommend it any more. And your logic there makes no sense. At what point does "still" matter? It used to be recommended by more people. It has been falling out of favor as more and more organizations stop recommending it as there is no evidence to support it. The fact that a few haven't updated their guidelines yet doesn't make it supported by evidence.
