Table 1.
Survey results for familiarity of odor descriptors after translation to Portuguese language.
After using a Likert type scale ranging from 0 to 5 (0 = unknown, 5 = highly familiar), average results are presented in a percentage scale.

Table 3.
Sniffin´ Sticks-pt normative data from healthy participants in Portugal.
Fig 1.
Box plot of TDI score for 3 age groups and for women and men.
TDI = composite score of T, D and I. T = threshold; D = discrimination; I = Identification. The median (horizontal line) is shown within each box, the extreme of the “whiskers” indicate the central 95% of each observation. No other significant relations were observed.
Table 4.
Normative data of TDI discriminated by age and gender.
The cutoff point has been defined by the 10th percentile of the distribution of the scores in the age group 18–35 years.
Fig 2.
Box plot comparing TDI scores between the healthy participants group and the “hyposmic” control group.
TDI = composite score of T, D and I. T = threshold; D = discrimination; I = Identification.

Sniffin´ Sticks Portuguese version results for the hyposmic group.
Fig 3.
Area under the curve for TDI 0.86 (95%CI 0.81–0.91); Threshold 0.71 (95%CI 0.64–0.77); Discrimination 0.84 (95%CI 0.79–0.89); Identification 0.84 (95%CI 0.79–0.89), p<0.001.
TDI = composite score of T, D and I. T = threshold; D = discrimination; I = Identification.

A Bland Altman agreement plot for TDI and Identification scores for test and retest.
The middle horizontal line represents the mean, and the upper and lower lines the 95% confidence limits of the mean.

Cronbach alpha and ICC are good at 0.70 and above.
