Fig. 2: Expected performance of odor combinations selected by chance, based on length.

From: Predictive value of abbreviated olfactory tests in prodromal Parkinson disease

Fig. 2

The mean and 95% confidence interval for the expected AUC of a randomly selected combination of odors of a given length (1 odor to 40 odors) was computed (black) or estimated (gray). The performance of each proposed or commercially available subset is shown relative to these intervals (squares). Only the Pocket Smell Test Version B (PST-B, 4 items) was outside of the 95% confidence interval for length; but was within the 99% confidence interval (not shown).
