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.
