#dialysis_minutes_shortfall ⇒ Object

Note the profile here might be a NullHDProfile which will always return 0 for the prescribed time - so sessions with a missing profile always report a dialysis_time_shortfall of 0

#ufr ⇒ Object

This is fluid removed (ml) / HD time in hours eg 3.75 / dry weight (kg) The result is in ml/hr/kg. Note that fluid removed is entered in L so we need to convert to ml here.
