For risks of bias and the intervention, as you saw on Glameth through eloquently, there's a lot of effort went into this to try and reduce biases. Alistair: Could we have done it maybe more effectively? The two graphs that were displayed, it's challenging doing things in intensive care. A large number of these patients died early on.
