really PB?

loss of pressure = fall/injury. There are various possible explanations for the loss of pressure as for the fall. The point being that the result on it's own is insufficient to determine cause.

The point in this case is that the loss of pressure isn't definitive, so it can't rule in or out claims either way. Have to look elsewhere.
