Association between parosmia, gender, and OD with relevant
improvement in identification
We were then interested in identifying smell-loss related factors that
are associated with clinically relevant improvements in odour
identification function (defined as improvement greater or equal 3.0
points) at follow-up visit.
Binary logistic regression analysis revealed that relevant improvements
in identification were more likely in those that had lower baseline
olfactory function (aOR, 0.95; 95%CI, 0.90-0.99), female gender
compared to male (aOR, 0.46, 95%CI, 0.24-0.85), and those that had
parosmia at first visit (aOR, 2.23; 95%CI, 1.15-4.30).
