Figure 10

Quantiles of random results from the software-encoded olfactory test in the proposed odor threshold test modification with beginning the finding of the test’s start point at T_start = 8 instead of T_start = 16. The black vertical and horizontal lines indicate the 96th quantile, which is in this version the accepted limit for anosmia according to the empirical limits given in the actual olfactory test instructions (100,000 simulations). The yellow and blue lines indicate the 90th and 95th quantiles, respectively, for the random results of the soft-coded olfactory test. All combinations of the three subtests, odor threshold, discrimination and identification, T, D and I, respectively, are shown in panels (A–G). The figure has been created using the R software package (version 4.2.2 for Linux; https://CRAN.R-project.org/ (R Development Core Team¹⁹)) and the library “ggplot2” (https://cran.r-project.org/package=ggplot2 (Wickham²²)).
