Descriptive statistics of participants.
Figure 1.
Percentage of correctly identified odors.
Displayed are the percentages of correct identification of the 16-item odor identification test for all children (n = 537). The odors, which were chosen for the 14-item “Sniffin' Kids” test are marked in dark grey. Odors, which were excluded were significantly less often correctly identified and are displayed in light grey.
Figure 2.
Odor identification score and age groups.
The boxplot displays the mean odor identification score for all ages. The age groups I, II and III differ significantly by means of odor identification score, while no age difference was obtained within a group. (* = p<0.001).

Comparing anosmic and healthy children.
Odor identification scores of healthy children, dark grey, (n = 537) and congenital anosmic children, light grey, (n = 25) are shown (means, one standard deviation). Healthy children scored in average 11.22 (1.87) points on the “Sniffin' Kids” test, while congenital anosmic children scored 4.12 (1.59) points. This was significantly different with a p value <0.001.
