Association between C-reactive protein and pulmonary function in postmenopausal women

OBJECTIVES: The objective of this study is to investigate the association of CRP and impaired pulmonary function in postmenopausal women. METHODS: The study was carried out in Gangnam Severance Hospital in Korea between March 2006 and October 2008. A total of 5978 healthy women subjects (age range, 20-75 years) were recruited from Seoul.

We evaluated CRP as a categorical variable and constructed three groups (a very low risk group, CRP
