  1. The table shows the items assigned to ABC set “A” by computed ABC analyses of the rank products of odor property importance for the olfactory diagnosis. The left part of the table shows the most relevant odors and properties in descending order of occurrence in ABC set “A”. The right part of the table shows the opposite analysis, i.e., aiming at the odors and properties that were least distinctive between the olfactory diagnoses of normosmia versus hyposmia. The original data consisted of an odor and a rated perceptive property. The numbers in the table show how many times an odor or a perceptive property was assigned to ABC set “A”, i.e., to the set of most relevant items.
