In this example, Spirometry was used to evaluate lung function.  The  shows results from several spirometry tests using either a spirometer or a peak flow meter where only the best result is available.

Rows 1-2:Show the data in original units of measure in REORRES for the best result for spirometry tests with the predicted values in REORREF.
Rows 3-4:Show the data in original units of measure in REORRES of percent predicted tests as output by the spirometer device. REORREF is null as there are no reference results for percent predicted tests.
Row 5:Shows the data in original units of measure in REORRES for the peak flow test with the predicted values in REORREF.
