Olfactory function was assessed by the Sniffin\u2019 Sticks 12\u2010item test and MS was diagnosed according to the guidelines.

The prevalence of MS was 15.0%. CRS patients with MS were more likely to be older (51.2 vs. 46.8, <jats:italic>p<\/jats:italic>\u2009=\u2009.004), predominantly male (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) and have a higher proportion of olfactory dysfunction (62.1% vs. 44.1%, <jats:italic>p<\/jats:italic>\u2009=\u2009.018) than those without MS. In multivariate logistic regression analysis, MS was associated with olfactory dysfunction in CRS patients (OR: 2.06, 95% CI: 1.14\u20133.72, <jats:italic>p<\/jats:italic>\u2009=\u2009.016). This association remained significant after controlling for confounding factors.
