All statistical analyses were performed using IBM SPSS Statistics (version 20 for windows). The Chi-squared test, mean comparison, and a logistical regression were used to explore the links between olfactory or gustative disorders and variables (age, gender). For statistical significance, the p < 0.05 threshold was chosen. The performance of a binary classification of our method was measured by sensitivity and specificity percentages.
