... between January 2012 and December 2013. All children were administered the BTT and CC-SIT. ResultsZZUsing BTT, 69.62% of the sample was classified as moderate hyposmia. On the other hand, when CC-SIT was used, 45.57% of the sample was classified as moderate and 43.04% as mild hyposmia. CC-SIT and BTT scores were not correlated. Although gender and age were not taken into account in the test results, the CC-SIT could measure age-specific olfactory development. ConclusionZZOur study provides fundamental data on the clinical use of the CC-SIT and BTT in healthy Korean children.
