I would be shocked by this, but I just finished reading "Noise: A Flaw in Human Judgment" by Daniel Kahneman (the author of Thinking fast and slow") and therefore I'm not at all surprised. In the book they show many well-documented examples where experts (including doctors) are giving wildly different judgements on the same case. In this specific article there's another factor that compounds the problem; bias towards more expensive treatments.
