Comparison of olfactory recovery by sex, age, severity, and
duration of olfactory dysfunction
When the KVSS-II scores were adjusted for sex and degree of dysfunction,
OT showed a significant effect on the difference in the KVSSII score (p
< 0.05). Age, median duration, and LM score at baseline
assessment were not correlated with recovery of olfactory function in
univariable linear regression analysis. Following adjustment for the
degree of dysfunction and olfactory training factors, sex had no
correlation with the difference in KVSS-II score. The group with anosmia
at baseline assessment showed a significantly higher increase in KVSS-II
test results compared with the other patients. Table 3 shows descriptive
data for the outcomes.
