Values are average scores of the threshold test (T), the discrimination test (D) and the identification score (I) ± SD (standard deviation), and p value calculated according to the Wilcoxon test (p was considered significant for p<0.05).
Figure 1 : Comparison of the TDI scores with and without a mask for each participant in Group 1 (n=10) and 2 (n=10).
Values are total TDI scores for each subject. TDI: threshold (T), discrimination (D) and identification (I) score.
The dotted line refers to the only subject with increased olfactory performance with a mask.
: mean value of TDI scores with and without a mask;
: TDI difference with and without a mask >5;
: TDI difference with and without a mask ≤5
