The developers sampled obvious cases og hypotension and nonhypotension, and trained the model to distinguish those. And also validated it on data that was similarly dichotomous. In reality the outcome is often between these two scenarios.

Random open ended discussion can be good, but I bet it's wise to assume tht most random musings arent really as interesting as you might think.
In any case thanks for clarifying.
