Summary of Cut Points for establishing MCID in the three PF scale ranges (0–25, 30–80, 85–100). In each Panel, if DeltaPF/se-D is less than the lower limit then that loss is considered clinically important. If DeltaPF/se-D is greater than the upper limit then that gain in PF is considered clinically important. The different cut points for the different baseline PF score ranges reflect different interpretations of the importance of change based on the patient’s starting point.
