**Comments:** This element is typically defined by the measure, but reproduced here to ensure the measure score can be interpreted. The element is labeled as a modifier because it changes the interpretation of the reported measure score. Note also that a MeasureReport instance includes the improvementNotation as defined by the Measure being reported. It is duplicated in the MeasureReport because it is a critical aspect of interpreting the measure score but it is not intended to reflect whether the measure report is an increase or decrease.
