  • Each subtype is compared with the 2716 subjects without any current cough.

  • ORs are presented if p<0.10. Multivariate logistic regression analysis with backward directed stepwise process.

  • *P<0.05, **P<0.01, ***P<0.001.

  • †OR is expressed per one somatic symptom.

  • ‡OR is expressed per one decade.

  • NS, not significant (p>0.10).
