Recent approaches in this field emphasize the importance of reducing the time and cost devoted to olfactory testing procedures. Hence, the aim of the present study was to examine the reliability and basic characteristics of Digital Scent Device 20 (DSD-20), an innovative olfactory test consisting of 20 \u201cuniversal odors\u201d, in a European population.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A total of 88 participants (mean age\u2009=\u200945.1, SD\u2009=\u200920.3) volunteered for the study.

Furthermore, the correlation coefficient between DSD-20 test and retest was very high (<jats:italic>R<\/jats:italic>\u2009=\u2009.88, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), which was additionally confirmed by a Bland-Altman plot.
